[[Image:rhic-tunnel.jpg|600px|Image: 600 pixels|center]]''[[At Brookhaven National Lab’s Relativistic Heavy Ion Collider (RHIC), physicists from around the world study what the universe may have looked like moments after its creation, from the smallest subatomic particles to the largest stars.]]'' <br />
<br />
<br />
Stony Brook University, in collaboration with Brookhaven National Laboratory (BNL), Cornell University and FERMI National Accelerator Laboratory, has established the Ernest Courant Traineeship in Accelerator Science & Engineering. The program is supported by a $2.9 million, five-year grant from the High Energy Office of the U.S. Department of Energy (DOE).<br />
<br />
The new program is named after renowned accelerator physicist Ernest Courant who, as a long-time physicist at BNL, laid the foundation of modern accelerator science. Courant also taught for 20 years as an adjunct professor at Stony Brook. The traineeship is offered through the Center for Accelerator Physics and Education (CASE).<br />
<br />
CASE is a joint center between BNL and Stony Brook, with three main goals of training scientists and engineers with the aim of advancing the field of accelerator science, developing a unique educational program that will provide broad access to research accelerators, and expanding interdisciplinary research and education programs utilizing accelerators.<br />
<br />
CASE focuses on four specific areas identified by the DOE as “mission critical workforce needs in accelerator science and engineering”: physics of large accelerators and systems engineering; superconducting radiofrequency accelerator physics and engineering; radiofrequency power system engineering; and cryogenic systems engineering, especially liquid helium systems.<br />
<br />
Vladimir Litvinenko, professor of physics in the Department of Physics and Astronomy and senior scientist at BNL, said the DOE is specifically looking to groom the next generation of scientists in those areas because “that’s where they have a shortage of skilled labor, and they really want us to help address that.”<br />
<br />
Research to understand and manipulate matter and energy using accelerators has led to the creation and commercial production of modern electronics and has had numerous applications in areas like radiation treatments for cancer, food safety, oil discovery, and searching for weapons of mass destruction. The understanding that accelerator science and technology has provided of matter and energy is also critical in space exploration and exploitation in terms of creating instrumentation, understanding space radiation, and creating new propulsion systems.<br />
<br />
The graduate-level curriculum consists of courses and practical training at accelerator facilities of the collaborating institutions, and thesis requirements. Each participant has a supervisor guide their training.<br />
<br />
Students in the traineeship program who complete four courses of the core program — 12 or more credits in accelerator science and engineering — and earn a B+ or higher in each course will be issued a certificate in Accelerator Science and Engineering with specializations including the four areas listed above.<br />
<br />
The traineeship is available to all students. Participants who are U.S. citizens or permanent U.S. residents are eligible for funding provided by the DOE grant. The expectation is that the traineeship can be completed in two years and students can pursue their research interest beyond the program.<br />
<br />
Litvinenko said the program will help students get a job involving accelerators, and appeals to a wide range of students from across the sciences.<br />
<br />
“One of my students who was interested in accelerators just really loved mechanical things,” said Litvinenko. “She was working in a garage before she came here. Other students might be interested in a more experimental hands-on experience, and others might be attracted to the diversity of the field, because accelerator science involve a broad range of sciences. It incorporates electrodynamics and mechanics, but there’s also quantum materials as well as complex systems like cryogenics.”<br />
<br />
“Participating in the CASE Accelerator School has been a great experience,” said Pietro Iapozzuto, a physics researcher at Stony Brook whose career dream has been to work in particle physics. “The classes teach you practical skills that will be needed to work in top government research facilities. The program has given me the opportunity to learn theoretical, computational, and experimental skills in order to become a proficient accelerator physicist. It also prepared me to participate in internship opportunities at the CERN laboratory and Brookhaven.”<br />
<br />
“I’m an electrical engineer but I have had the pleasure of working with physicists in recent years,” said Thomas Robertazzi, professor and IEEE Fellow, Department of Electrical and Computer Engineering. “What I have come to realize is if our society is ever to have the type of the appealing technologies we see in shows like Star Trek, it will take physicists like the ones in the traineeship program to discover and invent them.”<br />
<br />
Litvinenko said the current talent shortage is attributed to the attraction of engineers to the booming mobile device field.<br />
<br />
“So many engineers today are working on iPhones and other mobile devices,” he said. “But in accelerators we use really high-power systems, which is a very different scale and design. It’s older technology that’s no longer taught in regular universities, but still it’s extremely important. This is one of the things which we hope to offer next year to students.”<br />
<br />
Irina Petrushina ‘19, a research assistant professor who co-teaches a course on RF superconductivity for accelerators within the traineeship program, said the traineeship offers students a unique opportunity to explore the world of accelerator physics and engineering.<br />
<br />
“One can get a taste of accelerator physics and learn the basic concepts of accelerator operation in Fundamentals of Accelerator Physics, and more experienced students can learn about specific topics of interest such as cryogenic systems or computational aspects,” she said. “In addition to the direct interaction with the world-renowned experts, the students get to perform some hands-on experiments using one of the accelerators at BNL. The proximity and close collaboration between Stony Brook and BNL present an amazing opportunity to immerse yourself in the day-to-day life of an accelerator scientist.”<br />
<br />
Litvinenko said there is also a very practical aspect to the program: “Many of our students are landing jobs before graduation. I think this is not always true about academia and graduates and this may be reason why this certificate and the very real possibility of finding a good job is an additional attraction. In the end, students want to have a successful career.”</div>YichaoJinghttp://case.physics.stonybrook.edu/index.php?title=Ernest_courant_traineeship_main&diff=3829Ernest courant traineeship main2021-12-02T17:43:28Z<p>YichaoJing: </p>

== '''Why Particle Accelerators?''' ==<br />
<br />
[[Image:Cosmotron.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
Particle accelerators are a futuristic technology that has many uses including for science, engineering, medicine and industrial applications. There are about 30,000 accelerators of all sizes in the world. Finding trained people who can understand, operate and engineer such systems is a problem. What is a particle accelerator? It is a circular or straight (linear) tube containing a vacuum in which atomic particles (i.e. electrons, protons or ions) can be accelerated to high speed using electric and/or magnetic fields. Research accelerators can be measured in miles. Many other accelerators are much smaller. What can the particle accelerators be used for? Some applications include: <br />

'''Dr. Irina Petrushina''', PhD 2019<br />
<br />
[[Image:IrinaPetrushina.png|600px|Image: 1200 pixels|center]]<br />
<br />
What kind of career can a love of mathematics lead to? For Irina Petrushina it led to being a Research Scientist and Research Assistant Professor at Stony Brook University working on accelerator science and engineering. In high school she enjoyed languages and literature and played in the local theatre but her favorite subject by far was mathematics. This prompted her to seek education that would use a great deal of mathematics. Instead of working in pure math though she pursued career in physics as it uses mathematics to communicate the laws of nature, as she puts it.<br />

'''Dr. Rama Calaga''', PhD 2016<br />
<br />
[[Image:Rama-pic1.jpeg|400px|Image: 1200 pixels|center]]<br />
<br />
As a child in India, Rama Calaga was fascinated by physics and astronomy. He admits though that his perception of what physics was during his youth was more a fascination than reality. At Truman State in Missouri as an undergraduate student, he benefited from a close knit physics community of 7 professors and only 8 students. Rama thinks he was motivated to go to graduate school and study for a Ph.D thanks to all the professors at Truman who spent countless hours on the few physics students. He developed an interest in particle physics through a Research Experiences for Undergraduates (REU) program that is supported by the National Science Foundation. It introduced him to the practical world of experimental physics that is normally not obvious during undergraduate studies. Rama received his PhD in physics in 2016 from Stony Brook University.<br />

'''Kristina Finnelli'''<br />
<br />
[[Image:Finnelli Kristina.PNG|600px|Image: 1200 pixels|center]]<br />
<br />
I am an MSI (masters of science in instrumentation) student working with Professor Thomas Hemmick.<br />
<br />
My research project is to help design the line laser calibration system for the Time Projection Chamber (TPC), which will be the central tracker of the sPHENIX detector at RHIC. A compact, steerable, ionizing laser calibration system will be used to provide a known track that allows us to study the evolving components of the distortion throughout the TPC. I have been working on simulations of this system so we can understand how to improve our calibration efforts and what the limits will be.<br />
<br />
I think receiving a certification specifically in accelerator science and engineering will be helpful in standing out in that field.<br />
<br />
I am about to be finished with the courses necessary for the traineeship but will be continuing research for at least a semester.<br />
<br />
The financial assistance has allowed me to focus more on what I am learning and my research, where otherwise I may not have been able to. This will leave me in a better place once I graduate. I think if a student is already interested in focusing on accelerator physics, there is no reason not to apply for the traineeship program; taking additional classes will prepare you better if this is what you want your career to be, and leaving graduate school with a certificate will help you find a job later.<br />
<br />
<br />
'''Pietro Iapozzuto'''<br />
<br />
[[Image:Iapozzuto Pietro.jpeg|600px|Image: 1200 pixels|center]]<br />
<br />
I am pursuing a masters degree.<br />
<br />
My project involves Plasma Wakefield Acceleration. The advancement of compact accelerators will have tremendous impact in the medical field. My responsibilities were to build a plasma Wakefield chamber, design and install components such as the differential pumping system, and the beam profile monitor system.<br />
<br />
Participating in the program trained me in specific classes that otherwise I would have not taken and makes me knowledgeable in the current developments in the field. It helps in learning the jargon and gives one a basis to start doing research where otherwise it might be difficult understanding even group meetings. It also allows one to interact and speak with specialists in the field. My career goal is to become a professor and research scientist working in a government lab in the accelerator field.<br />
<br />
I am 3 credits away from finishing the traineeship<br />
<br />
The traineeship allowed me to consider a field in accelerator physics. I like that the professors are from different locations which give a different perspective and gives variety. The classes are condensed in a big time slot once a week which I like.<br />
<br />
The traineeship program changes things up from the regular Stony Brook classes, which do not give you specialized knowledge for your research. If you are interested in accelerators you need to have a background to understand the jargon and the technicalities and to be able to communicate. This program teaches you that. Again I like that the professors are from different locations which gives diversity and also networking potential.<br />

<br />
[[Image:Kingan Arun.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
I am a masters student working with Axel Drees.<br />
<br />
My research is on analyzing the data from the PHENIX experiment on the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. Specifically I am studying proton-gold collisions and measuring the direct photon yield so as to better understand the onset of Quark Gluon Plasma (QGP) in heavy ion collisions. My day to day responsibilities consist of writing and fine tuning the analysis code.<br />
<br />
The traineeship provided a comprehensive education in accelerator science, which has clear applications to studying heavy ion collisions (i.e. the collision part). While it is unclear at the moment whether I will continue studying heavy ion collisions throughout my PhD and beyond, accelerator science also has applications in numerous other fields like material science, biology etc. I am sure in whatever area of research I end up in, the information I’ve learned through this traineeship will be invaluable.<br />
<br />
I will be finishing the program at the end of this semester<br />
<br />
I particularly enjoyed the introductory classes. They provided information over a broad scope, which I found to be the most interesting. Particularly the lessons on all the different applications of accelerators were the best.<br />
<br />
Accelerator science has applications in almost all areas of STEM. Wherever your personal research interests lie, participating in this program will give you a well-rounded education which will ultimately aid you in your research.<br />

<br />
I am a masters of science in instrumentation student.<br />
<br />
My research project involves the diffuse laser system for the sPHENIX TPC (Time Projection Chamber). The diffuse laser system will allow us to monitor dynamic space charge inside the TPC. My responsibilities lie with ensuring adequate light uniformity on the central membrane, and certain aspects of the manufacturing of the central membrane.<br />
<br />
I think it is important to understand the systems we are using on a large scale. I intend to work with a national lab, either after pursing a PhD, or directly after my MSI program.<br />
<br />
I have nearly completed the traineeship program requirements. My masters will continue for one more year.<br />
<br />
There are interesting classes to take and lots of people active in the field teaching us. I wish I had been able to get some more hands on experience though.<br />
<br />
It is an interesting and short program. It is funded by the US Dept. of Energy and financial support is a possibility for US citizens and permanent residents.<br />

<br />
I am a PhD student. I work with Dr. Y. Semertzidis, Dr. W. Morse and Dr. F. Meot<br />
<br />
My research project is to provide design and computational support in the proton EDM project, with a strong focus on spin dynamics in the storage ring and impact on the design and specifications regarding its optical components.<br />
<br />
By participating the Ernest Courant Traineeship program, I gain fruitful theoretical knowledge and hands-on simulation experience in the field of accelerator physics. The Ernest Courant Traineeship program improves my academic knowledge and boosts my technological skills towards my research career of accelerator physics. My career goal is to be a computational accelerator physicist.<br />
<br />
I have been in the program one semester (starting from Spring 2021)<br />
<br />
Besides the funding opportunities, I gain broad academic knowledge in accelerator physics from various courses (Stony Brook and USPAS), I also receive much useful information that would help me prepare to pursue my career goal.<br />
<br />
The Ernest Courant Traineeship program educates students to be accelerator physicists from the professional perspective. It helps students who are interested in accelerator physics explore their career in this area.<br />

<br />
I am working on a research project at Brookhaven National Laboratory (BNL). The project is related to particle accelerator research. The research will be important for the current collider at BNL to increase its luminosity. My responsibilities are to operate, design and simulate the performance of the accelerator.<br />
<br />
My career goal is to become an Accelerator Physicist. The traineeship program gives me the opportunity to work with scientists around the world and gain many valuable experiences.<br />
<br />
I finished the program and joined Brookhaven National Laboratory as full-time this year.<br />
<br />
The best part of the traineeship program is that I can work with scientists around the world on a project which is closely relate to current physics research.<br />
<br />
I will highly recommend this program to other students. Students can work with people who are really good at this area. Particle accelerator research is also very important part of next generation physics research.</div>YichaoJinghttp://case.physics.stonybrook.edu/index.php?title=Next_generation_talent&diff=3828Next generation talent2021-12-02T17:41:48Z<p>YichaoJing: /* Developing the Next Generation of Particle Accelerator Talent */</p>

“One can get a taste of accelerator physics and learn the basic concepts of accelerator operation in Fundamentals of Accelerator Physics, and more experienced students can learn about specific topics of interest such as cryogenic systems or computational aspects,” she said. “In addition to the direct interaction with the world-renowned experts, the students get to perform some hands-on experiments using one of the accelerators at BNL. The proximity and close collaboration between Stony Brook and BNL present an amazing opportunity to immerse yourself in the day-to-day life of an accelerator scientist.”<br />
<br />
Litvinenko said there is also a very practical aspect to the program: “Many of our students are landing jobs before graduation. I think this is not always true about academia and graduates and this may be reason why this certificate and the very real possibility of finding a good job is an additional attraction. In the end, students want to have a successful career.”</div>YichaoJinghttp://case.physics.stonybrook.edu/index.php?title=Next_generation_talent&diff=3826Next generation talent2021-12-02T17:38:40Z<p>YichaoJing: /* Developing the Next Generation of Particle Accelerator Talent */</p>

<br />
Stony Brook University, in collaboration with Brookhaven National Laboratory (BNL), Cornell University and FERMI National Accelerator Laboratory, has established the Ernest Courant Traineeship in Accelerator Science & Engineering. The program is supported by a $2.9 million, five-year grant from the High Energy Office of the U.S. Department of Energy (DOE).<br />
<br />
The new program is named after renowned accelerator physicist Ernest Courant who, as a long-time physicist at BNL, laid the foundation of modern accelerator science. Courant also taught for 20 years as an adjunct professor at Stony Brook. The traineeship is offered through the Center for Accelerator Physics and Education (CASE).<br />
<br />
CASE is a joint center between BNL and Stony Brook, with three main goals of training scientists and engineers with the aim of advancing the field of accelerator science, developing a unique educational program that will provide broad access to research accelerators, and expanding interdisciplinary research and education programs utilizing accelerators.<br />
<br />
CASE focuses on four specific areas identified by the DOE as “mission critical workforce needs in accelerator science and engineering”: physics of large accelerators and systems engineering; superconducting radiofrequency accelerator physics and engineering; radiofrequency power system engineering; and cryogenic systems engineering, especially liquid helium systems.<br />
<br />
Vladimir Litvinenko, professor of physics in the Department of Physics and Astronomy and senior scientist at BNL, said the DOE is specifically looking to groom the next generation of scientists in those areas because “that’s where they have a shortage of skilled labor, and they really want us to help address that.”<br />
<br />
Research to understand and manipulate matter and energy using accelerators has led to the creation and commercial production of modern electronics and has had numerous applications in areas like radiation treatments for cancer, food safety, oil discovery, and searching for weapons of mass destruction. The understanding that accelerator science and technology has provided of matter and energy is also critical in space exploration and exploitation in terms of creating instrumentation, understanding space radiation, and creating new propulsion systems.<br />
<br />
The graduate-level curriculum consists of courses and practical training at accelerator facilities of the collaborating institutions, and thesis requirements. Each participant has a supervisor guide their training.<br />
<br />
Students in the traineeship program who complete four courses of the core program — 12 or more credits in accelerator science and engineering — and earn a B+ or higher in each course will be issued a certificate in Accelerator Science and Engineering with specializations including the four areas listed above.<br />
<br />
The traineeship is available to all students. Participants who are U.S. citizens or permanent U.S. residents are eligible for funding provided by the DOE grant. The expectation is that the traineeship can be completed in two years and students can pursue their research interest beyond the program.<br />
<br />
Litvinenko said the program will help students get a job involving accelerators, and appeals to a wide range of students from across the sciences.<br />
<br />
“One of my students who was interested in accelerators just really loved mechanical things,” said Litvinenko. “She was working in a garage before she came here. Other students might be interested in a more experimental hands-on experience, and others might be attracted to the diversity of the field, because accelerator science involve a broad range of sciences. It incorporates electrodynamics and mechanics, but there’s also quantum materials as well as complex systems like cryogenics.”<br />
<br />
“Participating in the CASE Accelerator School has been a great experience,” said Pietro Iapozzuto, a physics researcher at Stony Brook whose career dream has been to work in particle physics. “The classes teach you practical skills that will be needed to work in top government research facilities. The program has given me the opportunity to learn theoretical, computational, and experimental skills in order to become a proficient accelerator physicist. It also prepared me to participate in internship opportunities at the CERN laboratory and Brookhaven.”<br />
<br />
“I’m an electrical engineer but I have had the pleasure of working with physicists in recent years,” said Thomas Robertazzi, professor and IEEE Fellow, Department of Electrical and Computer Engineering. “What I have come to realize is if our society is ever to have the type of the appealing technologies we see in shows like Star Trek, it will take physicists like the ones in the traineeship program to discover and invent them.”<br />
<br />
Litvinenko said the current talent shortage is attributed to the attraction of engineers to the booming mobile device field.<br />
<br />
“So many engineers today are working on iPhones and other mobile devices,” he said. “But in accelerators we use really high-power systems, which is a very different scale and design. It’s older technology that’s no longer taught in regular universities, but still it’s extremely important. This is one of the things which we hope to offer next year to students.”<br />

<br />
Particle accelerators are a futuristic technology that has many uses including for science, engineering, medicine and industrial applications. There are about 30,000 accelerators of all sizes in the world. Finding trained people who can understand, operate and engineer such systems is a problem. What is a particle accelerator? It is a circular or straight (linear) tube containing a vacuum in which atomic particles (i.e. electrons, protons or ions) can be accelerated to high speed using electric and/or magnetic fields. Research accelerators can be measured in miles. Many other accelerators are much smaller. What can the particle accelerators be used for? Some applications include: <br />

<br />
What kind of career can a love of mathematics lead to? For Irina Petrushina it led to being a Research Scientist and Research Assistant Professor at Stony Brook University working on accelerator science and engineering. In high school she enjoyed languages and literature and played in the local theatre but her favorite subject by far was mathematics. This prompted her to seek education that would use a great deal of mathematics. Instead of working in pure math though she pursued career in physics as it uses mathematics to communicate the laws of nature, as she puts it.<br />

<br />
As a child in India, Rama Calaga was fascinated by physics and astronomy. He admits though that his perception of what physics was during his youth was more a fascination than reality. At Truman State in Missouri as an undergraduate student, he benefited from a close knit physics community of 7 professors and only 8 students. Rama thinks he was motivated to go to graduate school and study for a Ph.D thanks to all the professors at Truman who spent countless hours on the few physics students. He developed an interest in particle physics through a Research Experiences for Undergraduates (REU) program that is supported by the National Science Foundation. It introduced him to the practical world of experimental physics that is normally not obvious during undergraduate studies. Rama received his PhD in physics in 2016 from Stony Brook University.<br />

<br />
I am an MSI (masters of science in instrumentation) student working with Professor Thomas Hemmick.<br />
<br />
My research project is to help design the line laser calibration system for the Time Projection Chamber (TPC), which will be the central tracker of the sPHENIX detector at RHIC. A compact, steerable, ionizing laser calibration system will be used to provide a known track that allows us to study the evolving components of the distortion throughout the TPC. I have been working on simulations of this system so we can understand how to improve our calibration efforts and what the limits will be.<br />
<br />
I think receiving a certification specifically in accelerator science and engineering will be helpful in standing out in that field.<br />
<br />
I am about to be finished with the courses necessary for the traineeship but will be continuing research for at least a semester.<br />
<br />
The financial assistance has allowed me to focus more on what I am learning and my research, where otherwise I may not have been able to. This will leave me in a better place once I graduate. I think if a student is already interested in focusing on accelerator physics, there is no reason not to apply for the traineeship program; taking additional classes will prepare you better if this is what you want your career to be, and leaving graduate school with a certificate will help you find a job later.<br />

<br />
I am pursuing a masters degree.<br />
<br />
My project involves Plasma Wakefield Acceleration. The advancement of compact accelerators will have tremendous impact in the medical field. My responsibilities were to build a plasma Wakefield chamber, design and install components such as the differential pumping system, and the beam profile monitor system.<br />
<br />
Participating in the program trained me in specific classes that otherwise I would have not taken and makes me knowledgeable in the current developments in the field. It helps in learning the jargon and gives one a basis to start doing research where otherwise it might be difficult understanding even group meetings. It also allows one to interact and speak with specialists in the field. My career goal is to become a professor and research scientist working in a government lab in the accelerator field.<br />
<br />
I am 3 credits away from finishing the traineeship<br />
<br />
The traineeship allowed me to consider a field in accelerator physics. I like that the professors are from different locations which give a different perspective and gives variety. The classes are condensed in a big time slot once a week which I like.<br />
<br />
The traineeship program changes things up from the regular Stony Brook classes, which do not give you specialized knowledge for your research. If you are interested in accelerators you need to have a background to understand the jargon and the technicalities and to be able to communicate. This program teaches you that. Again I like that the professors are from different locations which gives diversity and also networking potential.<br />

<br />
[[Image:Kingan Arun.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
I am a masters student working with Axel Drees.<br />
<br />
My research is on analyzing the data from the PHENIX experiment on the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. Specifically I am studying proton-gold collisions and measuring the direct photon yield so as to better understand the onset of Quark Gluon Plasma (QGP) in heavy ion collisions. My day to day responsibilities consist of writing and fine tuning the analysis code.<br />
<br />
The traineeship provided a comprehensive education in accelerator science, which has clear applications to studying heavy ion collisions (i.e. the collision part). While it is unclear at the moment whether I will continue studying heavy ion collisions throughout my PhD and beyond, accelerator science also has applications in numerous other fields like material science, biology etc. I am sure in whatever area of research I end up in, the information I’ve learned through this traineeship will be invaluable.<br />
<br />
I will be finishing the program at the end of this semester<br />
<br />
I particularly enjoyed the introductory classes. They provided information over a broad scope, which I found to be the most interesting. Particularly the lessons on all the different applications of accelerators were the best.<br />
<br />
Accelerator science has applications in almost all areas of STEM. Wherever your personal research interests lie, participating in this program will give you a well-rounded education which will ultimately aid you in your research.<br />

<br />
I am a masters of science in instrumentation student.<br />
<br />
My research project involves the diffuse laser system for the sPHENIX TPC (Time Projection Chamber). The diffuse laser system will allow us to monitor dynamic space charge inside the TPC. My responsibilities lie with ensuring adequate light uniformity on the central membrane, and certain aspects of the manufacturing of the central membrane.<br />
<br />
I think it is important to understand the systems we are using on a large scale. I intend to work with a national lab, either after pursing a PhD, or directly after my MSI program.<br />
<br />
I have nearly completed the traineeship program requirements. My masters will continue for one more year.<br />
<br />
There are interesting classes to take and lots of people active in the field teaching us. I wish I had been able to get some more hands on experience though.<br />
<br />
It is an interesting and short program. It is funded by the US Dept. of Energy and financial support is a possibility for US citizens and permanent residents.<br />

<br />
I am a PhD student. I work with Dr. Y. Semertzidis, Dr. W. Morse and Dr. F. Meot<br />
<br />
My research project is to provide design and computational support in the proton EDM project, with a strong focus on spin dynamics in the storage ring and impact on the design and specifications regarding its optical components.<br />
<br />
By participating the Ernest Courant Traineeship program, I gain fruitful theoretical knowledge and hands-on simulation experience in the field of accelerator physics. The Ernest Courant Traineeship program improves my academic knowledge and boosts my technological skills towards my research career of accelerator physics. My career goal is to be a computational accelerator physicist.<br />
<br />
I have been in the program one semester (starting from Spring 2021)<br />
<br />
Besides the funding opportunities, I gain broad academic knowledge in accelerator physics from various courses (Stony Brook and USPAS), I also receive much useful information that would help me prepare to pursue my career goal.<br />
<br />
The Ernest Courant Traineeship program educates students to be accelerator physicists from the professional perspective. It helps students who are interested in accelerator physics explore their career in this area.<br />

<br />
I am a masters student.<br />
<br />
I am working on a research project at Brookhaven National Laboratory (BNL). The project is related to particle accelerator research. The research will be important for the current collider at BNL to increase its luminosity. My responsibilities are to operate, design and simulate the performance of the accelerator.<br />
<br />
My career goal is to become an Accelerator Physicist. The traineeship program gives me the opportunity to work with scientists around the world and gain many valuable experiences.<br />
<br />
I finished the program and joined Brookhaven National Laboratory as full-time this year.<br />
<br />
The best part of the traineeship program is that I can work with scientists around the world on a project which is closely relate to current physics research.<br />
<br />
I will highly recommend this program to other students. Students can work with people who are really good at this area. Particle accelerator research is also very important part of next generation physics research.</div>YichaoJinghttp://case.physics.stonybrook.edu/index.php?title=File:PHY554_Lecture18_F2021.pdf&diff=3744File:PHY554 Lecture18 F2021.pdf2021-10-26T23:40:22Z<p>YichaoJing: </p>

<br />
10+ S.Y. Lee's and Edwards-Syphers' books are available in BNL library.<br />
<br />
== Course Description ==<br />
<br />
*Introduction to accelerator physics <br />You will have a glance into the history of accelerators and will learn about a variety of accelerators from electrostatic TV-tubes to gigantic atom and nuclear smashers. Basic figures of merit will be introduced (center of mass energy, luminosity, accelerating gradient, etc.) You will learn general principles behing linear accelerators and circular accelerators, their relative advantages and disadvantages.<br />
<br />
*Radio frequency cavities, linacs, superconducting RF accelerators <br />This part of the course will be dedicated to physics and technology of accelerating structures. You will learn basic principles of using radio frequency electromagnetic fields to accelerate particles to very high energies. Different types of accelerating structures will be introduced. You will also learn about brand new direction in linear accelerators – so-called energy recovery linacs. As many modern accelerators are based on superconducting RF (SRF) technlogy, you will learn fundamentals of the SRF accelerators and their advantages over conventional (normal conductoing) RF accelerators.<br />
<br />
*Linear transverse beam dynamics <br />This part of the course will be dedicated to detailed description of linear dynamics of particles in accelerators. You will learn about similarity of particles motion to an oscillator with time-dependent rigidity, matrix optics of various elements in accelerators, equation for beam envelopes and stability of periodic (circular) motion of the particles. Here you find a number of analogies with planetary motion, including oscillation of Earth’s moon. You will learn some “standards” of the accelerator physics – betatron tunes and beta-function and their importance in circular accelerators.<br />
<br />
*Nonlinear transverse beam dynamics <br />This lecture will open door in fascinating and never-ending elegance and complexity on nonlinear beam dynamics. You will learn about non-linear resonances, which may affect stability of the particles and about their location on the tune diagram. You will learn about chromatic (energy dependent) effects, use of non-linear elements to compensate them, and about problems created by introducing them. Some of traditional perturbation theory methods will be introduced during this lecture. <br />
<br />
*Longitudinal beam dynamics <br />If you were ever wondering why Saturn rings do not collapse into one large ball of rock under gravitational attraction – this where you will learn of the effect so-called negative mass in longitudinal motion of particles. You will also learn about so-called synchrotron oscillations, which are have a lot of similarity with pendulum motion. One more “tunes” to remember about - synchrotron tune.<br />
<br />
*Radiation effects <br />Charged particles going around an accelerator do radiate when their trajectory is bent – hence, there is entire range of topics arising from this fact. It goes from such effect as radiation damping of the particle oscillations, quantum excitation of such oscillation to the use of this extraordinary radiation as cutting-edge research tool. We will look both into positive (usefulness of synchrotron and FEL radiation) and negative (limiting the energy of electron storage rings) aspects of this natural phenomenon.<br />
<br />
*Accelerator applications <br />We will devote this part of the course to the discussion of variety of accelerator application, among which are accelerators for nuclear and particle physics, X-ray light sources, accelerators for medical uses, etc. You will also learn about future accelerators at the energy and intensity forntiers as well as about new methods of particle acceleration.<br />

<br />
== Course Description ==<br />
<br />
*Introduction to accelerator physics <br />You will have a glance into the history of accelerators and will learn about a variety of accelerators from electrostatic TV-tubes to gigantic atom and nuclear smashers. Basic figures of merit will be introduced (center of mass energy, luminosity, accelerating gradient, etc.) You will learn general principles behing linear accelerators and circular accelerators, their relative advantages and disadvantages.<br />
<br />
*Radio frequency cavities, linacs, superconducting RF accelerators <br />This part of the course will be dedicated to physics and technology of accelerating structures. You will learn basic principles of using radio frequency electromagnetic fields to accelerate particles to very high energies. Different types of accelerating structures will be introduced. You will also learn about brand new direction in linear accelerators – so-called energy recovery linacs. As many modern accelerators are based on superconducting RF (SRF) technlogy, you will learn fundamentals of the SRF accelerators and their advantages over conventional (normal conductoing) RF accelerators.<br />
<br />
*Linear transverse beam dynamics <br />This part of the course will be dedicated to detailed description of linear dynamics of particles in accelerators. You will learn about similarity of particles motion to an oscillator with time-dependent rigidity, matrix optics of various elements in accelerators, equation for beam envelopes and stability of periodic (circular) motion of the particles. Here you find a number of analogies with planetary motion, including oscillation of Earth’s moon. You will learn some “standards” of the accelerator physics – betatron tunes and beta-function and their importance in circular accelerators.<br />
<br />
*Nonlinear transverse beam dynamics <br />This lecture will open door in fascinating and never-ending elegance and complexity on nonlinear beam dynamics. You will learn about non-linear resonances, which may affect stability of the particles and about their location on the tune diagram. You will learn about chromatic (energy dependent) effects, use of non-linear elements to compensate them, and about problems created by introducing them. Some of traditional perturbation theory methods will be introduced during this lecture. <br />
<br />
*Longitudinal beam dynamics <br />If you were ever wondering why Saturn rings do not collapse into one large ball of rock under gravitational attraction – this where you will learn of the effect so-called negative mass in longitudinal motion of particles. You will also learn about so-called synchrotron oscillations, which are have a lot of similarity with pendulum motion. One more “tunes” to remember about - synchrotron tune.<br />
<br />
*Radiation effects <br />Charged particles going around an accelerator do radiate when their trajectory is bent – hence, there is entire range of topics arising from this fact. It goes from such effect as radiation damping of the particle oscillations, quantum excitation of such oscillation to the use of this extraordinary radiation as cutting-edge research tool. We will look both into positive (usefulness of synchrotron and FEL radiation) and negative (limiting the energy of electron storage rings) aspects of this natural phenomenon.<br />
<br />
*Accelerator applications <br />We will devote this part of the course to the discussion of variety of accelerator application, among which are accelerators for nuclear and particle physics, X-ray light sources, accelerators for medical uses, etc. You will also learn about future accelerators at the energy and intensity forntiers as well as about new methods of particle acceleration.<br />

<br />
A course in Cryogenic Systems and Design is offering students entrée into a much in demand area that is essential in a diverse range of applications. Cryogenics involves the scientific basis, design and practical applications of low-temperature systems and components. It is used in space exploration, high energy physics, particle accelerators and detectors, fusion energy systems, hydrogen based clean energy systems, liquefied natural gas, quantum computing, sensors, medicine and food preservation to name a few applications. There are diverse opportunities and career tracks one can pursue in this field including research, technology, and business. <br />
<br />
The online course is offered by four experts from Fermi National Accelerator Laboratory (FNAL). They are Arkadiy Klebaner, Ram Dhuley, Matthew Hollister and David Montanari. Together they have decades of experience in the cryogenic area. They are led by Arkadiy Klebaner. The course is an online Stony Brook University graduate physics course with about 18 students attending in Fall 2021 both from the Stony Brook Ernest Courant Traineeship in Accelerator Science and Engineering program and from other universities and US National Laboratories. Eighteen students is a large size for a graduate physics course. The instructors feel this is indicative of interest both from students and from trained professionals.<br />
<br />
“Cryogenics” is a word of Greek origin (“Kryos” is frost and “Gen” is to generate). It is the science and technology of temperatures below 120 degrees Kelvin. The temperature of the universe is 2.7 degrees Kelvin. The lowest temperature ever achieved is 280 thousandth of a billionth degree Kelvin. Historically, globalization (world trade) stimulated a need for developing new refrigeration methods and advance thermal science. In 1877 air was liquified and in 1898 oxygen was liquified at 14 degrees Kelvin. Over the years a broad range of applications at various temperatures have been implemented.<br />
<br />
For a long time there has been a strong demand for people trained in cryogenics from both the US National Laboratories and from industry. People trained in cryogenics work in the design, engineering, and the operation of various cryogenic systems. New and upcoming areas include liquefaction and storage of hydrogen as a clean energy source, fuels and materials for supporting the growing area of space travel, the quest for human inhabitation of Mars, and nuclear fusion – all of which make use of cryogenics to a great extent. There are also a number of large physics projects in the multi-billion dollar range that heavily rely on people trained in cryogenics. These include LBNF (https://lbnf-dune.fnal.gov/), PIP-II (https://pip2.fnal.gov/) and the EIC (https://www.bnl.gov/eic/)<br />
<br />
This is a good demonstration of the appealing opportunities that await students and workers in today and tomorrow’s technological world.<br />

<br />
Stony Brook University in collaboration with Brookhaven National Laboratory (BNL), Cornell University (CU) and FERMI National Accelerator Laboratory (FNAL) is establishing the Ernest Courant Traineeship in Accelerator Science & Engineering supported by a 5-year grant from the High Energy Office of the US Department of Energy. This novel program is named after eminent accelerator physicist, Ernest Courant, who lay the foundation of modern accelerator science. At SBU the traineeship is a part of the Center for Accelerator Physics and Education (CASE) – the http://case.physics.stonybrook.edu/index.php/Main_Page <br />
<br />
The main goal of the program is to train scientists and engineers in the field of accelerator sciences with a focus in the four areas identified as the DOE Mission Critical Workforce Needs in Accelerator Science and Engineering: (a) Physics of large accelerators and systems engineering; (b) Superconducting radiofrequency accelerator physics and engineering; (c) Radiofrequency power system engineering and (d) Cryogenic systems engineering (especially liquid helium systems).<br />

== '''Why Particle Accelerators?''' ==<br />
<br />
[[Image:Cosmotron.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
Particle accelerators are a futuristic technology that has many uses including for science, engineering, medicine and industrial applications. There are about 30,000 accelerators of all sizes in the world. Finding trained people who can understand, operate and engineer such systems is a problem. What is a particle accelerator? It is a circular or straight (linear) tube containing a vacuum in which atomic particles (i.e. electrons, protons or ions) can be accelerated to high speed using electric and/or magnetic fields. Research accelerators can be measured in miles. Many other accelerators are much smaller. What can the particle accelerators be used for? Some applications include: <br />

<br />
What kind of career can a love of mathematics lead to? For Irina Petrushina it led to being a Research Scientist and Research Assistant Professor at Stony Brook University working on accelerator science and engineering. In high school she enjoyed languages and literature and played in the local theatre but her favorite subject by far was mathematics. This prompted her to seek education that would use a great deal of mathematics. Instead of working in pure math though she pursued career in physics as it uses mathematics to communicate the laws of nature, as she puts it.<br />

<br />
[[Image:Rama-pic1.jpeg|400px|Image: 1200 pixels|center]]<br />
<br />
As a child in India, Rama Calaga was fascinated by physics and astronomy. He admits though that his perception of what physics was during his youth was more a fascination than reality. At Truman State in Missouri as an undergraduate student, he benefited from a close knit physics community of 7 professors and only 8 students. Rama thinks he was motivated to go to graduate school and study for a Ph.D thanks to all the professors at Truman who spent countless hours on the few physics students. He developed an interest in particle physics through a Research Experiences for Undergraduates (REU) program that is supported by the National Science Foundation. It introduced him to the practical world of experimental physics that is normally not obvious during undergraduate studies. Rama received his PhD in physics in 2016 from Stony Brook University.<br />

'''Kristina Finnelli'''<br />
<br />
[[Image:Finnelli Kristina.PNG|600px|Image: 1200 pixels|center]]<br />
<br />
I am an MSI (masters of science in instrumentation) student working with Professor Thomas Hemmick.<br />
<br />
My research project is to help design the line laser calibration system for the Time Projection Chamber (TPC), which will be the central tracker of the sPHENIX detector at RHIC. A compact, steerable, ionizing laser calibration system will be used to provide a known track that allows us to study the evolving components of the distortion throughout the TPC. I have been working on simulations of this system so we can understand how to improve our calibration efforts and what the limits will be.<br />
<br />
I think receiving a certification specifically in accelerator science and engineering will be helpful in standing out in that field.<br />
<br />
I am about to be finished with the courses necessary for the traineeship but will be continuing research for at least a semester.<br />
<br />
The financial assistance has allowed me to focus more on what I am learning and my research, where otherwise I may not have been able to. This will leave me in a better place once I graduate. I think if a student is already interested in focusing on accelerator physics, there is no reason not to apply for the traineeship program; taking additional classes will prepare you better if this is what you want your career to be, and leaving graduate school with a certificate will help you find a job later.<br />

<br />
[[Image:Iapozzuto Pietro.jpeg|600px|Image: 1200 pixels|center]]<br />
<br />
I am pursuing a masters degree.<br />
<br />
My project involves Plasma Wakefield Acceleration. The advancement of compact accelerators will have tremendous impact in the medical field. My responsibilities were to build a plasma Wakefield chamber, design and install components such as the differential pumping system, and the beam profile monitor system.<br />
<br />
Participating in the program trained me in specific classes that otherwise I would have not taken and makes me knowledgeable in the current developments in the field. It helps in learning the jargon and gives one a basis to start doing research where otherwise it might be difficult understanding even group meetings. It also allows one to interact and speak with specialists in the field. My career goal is to become a professor and research scientist working in a government lab in the accelerator field.<br />
<br />
I am 3 credits away from finishing the traineeship<br />
<br />
The traineeship allowed me to consider a field in accelerator physics. I like that the professors are from different locations which give a different perspective and gives variety. The classes are condensed in a big time slot once a week which I like.<br />
<br />
The traineeship program changes things up from the regular Stony Brook classes, which do not give you specialized knowledge for your research. If you are interested in accelerators you need to have a background to understand the jargon and the technicalities and to be able to communicate. This program teaches you that. Again I like that the professors are from different locations which gives diversity and also networking potential.<br />

<br />
[[Image:Kingan Arun.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
I am a masters student working with Axel Drees.<br />
<br />
My research is on analyzing the data from the PHENIX experiment on the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. Specifically I am studying proton-gold collisions and measuring the direct photon yield so as to better understand the onset of Quark Gluon Plasma (QGP) in heavy ion collisions. My day to day responsibilities consist of writing and fine tuning the analysis code.<br />
<br />
The traineeship provided a comprehensive education in accelerator science, which has clear applications to studying heavy ion collisions (i.e. the collision part). While it is unclear at the moment whether I will continue studying heavy ion collisions throughout my PhD and beyond, accelerator science also has applications in numerous other fields like material science, biology etc. I am sure in whatever area of research I end up in, the information I’ve learned through this traineeship will be invaluable.<br />
<br />
I will be finishing the program at the end of this semester<br />
<br />
I particularly enjoyed the introductory classes. They provided information over a broad scope, which I found to be the most interesting. Particularly the lessons on all the different applications of accelerators were the best.<br />
<br />
Accelerator science has applications in almost all areas of STEM. Wherever your personal research interests lie, participating in this program will give you a well-rounded education which will ultimately aid you in your research.<br />

I am a masters of science in instrumentation student.<br />
<br />
My research project involves the diffuse laser system for the sPHENIX TPC (Time Projection Chamber). The diffuse laser system will allow us to monitor dynamic space charge inside the TPC. My responsibilities lie with ensuring adequate light uniformity on the central membrane, and certain aspects of the manufacturing of the central membrane.<br />
<br />
I think it is important to understand the systems we are using on a large scale. I intend to work with a national lab, either after pursing a PhD, or directly after my MSI program.<br />
<br />
I have nearly completed the traineeship program requirements. My masters will continue for one more year.<br />
<br />
There are interesting classes to take and lots of people active in the field teaching us. I wish I had been able to get some more hands on experience though.<br />
<br />
It is an interesting and short program. It is funded by the US Dept. of Energy and financial support is a possibility for US citizens and permanent residents.<br />

My research project is to provide design and computational support in the proton EDM project, with a strong focus on spin dynamics in the storage ring and impact on the design and specifications regarding its optical components.<br />
<br />
By participating the Ernest Courant Traineeship program, I gain fruitful theoretical knowledge and hands-on simulation experience in the field of accelerator physics. The Ernest Courant Traineeship program improves my academic knowledge and boosts my technological skills towards my research career of accelerator physics. My career goal is to be a computational accelerator physicist.<br />
<br />
I have been in the program one semester (starting from Spring 2021)<br />
<br />
Besides the funding opportunities, I gain broad academic knowledge in accelerator physics from various courses (Stony Brook and USPAS), I also receive much useful information that would help me prepare to pursue my career goal.<br />
<br />
The Ernest Courant Traineeship program educates students to be accelerator physicists from the professional perspective. It helps students who are interested in accelerator physics explore their career in this area.<br />

The best part of the traineeship program is that I can work with scientists around the world on a project which is closely relate to current physics research.<br />
<br />
I will highly recommend this program to other students. Students can work with people who are really good at this area. Particle accelerator research is also very important part of next generation physics research.</div>YichaoJinghttp://case.physics.stonybrook.edu/index.php?title=Ernest_courant_traineeship&diff=3670Ernest courant traineeship2021-10-01T18:58:12Z<p>YichaoJing: /* Ernest Courant Traineeship in Accelerator Science & Engineering */</p>

<br />
Stony Brook University in collaboration with Brookhaven National Laboratory (BNL), Cornell University (CU) and FERMI National Accelerator Laboratory (FNAL) is establishing the Ernest Courant Traineeship in Accelerator Science & Engineering supported by a 5-year grant from the High Energy Office of the US Department of Energy. This novel program is named after eminent accelerator physicist, Ernest Courant, who lay the foundation of modern accelerator science. At SBU the traineeship is a part of the Center for Accelerator Physics and Education (CASE) – the http://case.physics.stonybrook.edu/index.php/Main_Page <br />
<br />
The main goal of the program is to train scientists and engineers in the field of accelerator sciences with a focus in the four areas identified as the DOE Mission Critical Workforce Needs in Accelerator Science and Engineering: (a) Physics of large accelerators and systems engineering; (b) Superconducting radiofrequency accelerator physics and engineering; (c) Radiofrequency power system engineering and (d) Cryogenic systems engineering (especially liquid helium systems). <br />
<br />
The graduate level curriculum consists of courses and practical training at accelerator facilities of the collaborating institutions, and thesis requirements. Each of participant will have a supervisor to guide the training. Every graduate student – PhD, MS/MSI, ME - successfully completing the traineeship program will be issued a Certificate in Accelerator Science and Engineering with specializations including the four areas listed above.

== Textbook and ''suggested materials''==<br />
<br />
Textbook is to be decided from the following:<br />
*Accelerator Physics, by S. Y. Lee<br />
*An Introduction to the Physics of High Energy Accelerators, by D. A. Edwards and M. J. Syphers<br />
*''Introduction To The Physics Of Particle Accelerators'', by Mario Conte and William W Mackay <br />
*''Particle Accelerator Physics'', by Helmut Wiedemann<br />
*''The Physics of Particle Accelerators: An Introduction'', by Klaus Wille and Jason McFall<br />
<br />
10+ S.Y. Lee's and Edwards-Syphers' books are available in BNL library.<br />
<br />
== Course Description ==<br />
<br />
*Introduction to accelerator physics <br />You will have a glance into the history of accelerators and will learn about a variety of accelerators from electrostatic TV-tubes to gigantic atom and nuclear smashers. Basic figures of merit will be introduced (center of mass energy, luminosity, accelerating gradient, etc.) You will learn general principles behing linear accelerators and circular accelerators, their relative advantages and disadvantages.<br />
<br />
*Radio frequency cavities, linacs, superconducting RF accelerators <br />This part of the course will be dedicated to physics and technology of accelerating structures. You will learn basic principles of using radio frequency electromagnetic fields to accelerate particles to very high energies. Different types of accelerating structures will be introduced. You will also learn about brand new direction in linear accelerators – so-called energy recovery linacs. As many modern accelerators are based on superconducting RF (SRF) technlogy, you will learn fundamentals of the SRF accelerators and their advantages over conventional (normal conductoing) RF accelerators.<br />
<br />
*Linear transverse beam dynamics <br />This part of the course will be dedicated to detailed description of linear dynamics of particles in accelerators. You will learn about similarity of particles motion to an oscillator with time-dependent rigidity, matrix optics of various elements in accelerators, equation for beam envelopes and stability of periodic (circular) motion of the particles. Here you find a number of analogies with planetary motion, including oscillation of Earth’s moon. You will learn some “standards” of the accelerator physics – betatron tunes and beta-function and their importance in circular accelerators.<br />
<br />
*Nonlinear transverse beam dynamics <br />This lecture will open door in fascinating and never-ending elegance and complexity on nonlinear beam dynamics. You will learn about non-linear resonances, which may affect stability of the particles and about their location on the tune diagram. You will learn about chromatic (energy dependent) effects, use of non-linear elements to compensate them, and about problems created by introducing them. Some of traditional perturbation theory methods will be introduced during this lecture. <br />
<br />
*Longitudinal beam dynamics <br />If you were ever wondering why Saturn rings do not collapse into one large ball of rock under gravitational attraction – this where you will learn of the effect so-called negative mass in longitudinal motion of particles. You will also learn about so-called synchrotron oscillations, which are have a lot of similarity with pendulum motion. One more “tunes” to remember about - synchrotron tune.<br />
<br />
*Radiation effects <br />Charged particles going around an accelerator do radiate when their trajectory is bent – hence, there is entire range of topics arising from this fact. It goes from such effect as radiation damping of the particle oscillations, quantum excitation of such oscillation to the use of this extraordinary radiation as cutting-edge research tool. We will look both into positive (usefulness of synchrotron and FEL radiation) and negative (limiting the energy of electron storage rings) aspects of this natural phenomenon.<br />
<br />
*Accelerator applications <br />We will devote this part of the course to the discussion of variety of accelerator application, among which are accelerators for nuclear and particle physics, X-ray light sources, accelerators for medical uses, etc. You will also learn about future accelerators at the energy and intensity forntiers as well as about new methods of particle acceleration.<br />

[[Image:Rama-pic1.jpeg|400px|Image: 1200 pixels|center]]<br />
<br />
As a child in India, Rama Calaga was fascinated by physics and astronomy. He admits though that his perception of what physics was during his youth was more a fascination than reality. At Truman State in Missouri as an undergraduate student, he benefited from a close knit physics community of 7 professors and only 8 students. Rama thinks he was motivated to go to graduate school and study for a Ph.D thanks to all the professors at Truman who spent countless hours on the few physics students. He developed an interest in particle physics through a Research Experiences for Undergraduates (REU) program that is supported by the National Science Foundation. It introduced him to the practical world of experimental physics that is normally not obvious during undergraduate studies. Rama received his PhD in physics in 2016 from Stony Brook University.<br />

<br />
I am an MSI (masters of science in instrumentation) student working with Professor Thomas Hemmick.<br />
<br />
My research project is to help design the line laser calibration system for the Time Projection Chamber (TPC), which will be the central tracker of the sPHENIX detector at RHIC. A compact, steerable, ionizing laser calibration system will be used to provide a known track that allows us to study the evolving components of the distortion throughout the TPC. I have been working on simulations of this system so we can understand how to improve our calibration efforts and what the limits will be.<br />
<br />
I think receiving a certification specifically in accelerator science and engineering will be helpful in standing out in that field.<br />
<br />
I am about to be finished with the courses necessary for the traineeship but will be continuing research for at least a semester.<br />
<br />
The financial assistance has allowed me to focus more on what I am learning and my research, where otherwise I may not have been able to. This will leave me in a better place once I graduate. I think if a student is already interested in focusing on accelerator physics, there is no reason not to apply for the traineeship program; taking additional classes will prepare you better if this is what you want your career to be, and leaving graduate school with a certificate will help you find a job later.<br />

<br />
[[Image:Iapozzuto Pietro.jpeg|600px|Image: 1200 pixels|center]]<br />
<br />
I am pursuing a masters degree.<br />
<br />
My project involves Plasma Wakefield Acceleration. The advancement of compact accelerators will have tremendous impact in the medical field. My responsibilities were to build a plasma Wakefield chamber, design and install components such as the differential pumping system, and the beam profile monitor system.<br />
<br />
Participating in the program trained me in specific classes that otherwise I would have not taken and makes me knowledgeable in the current developments in the field. It helps in learning the jargon and gives one a basis to start doing research where otherwise it might be difficult understanding even group meetings. It also allows one to interact and speak with specialists in the field. My career goal is to become a professor and research scientist working in a government lab in the accelerator field.<br />
<br />
I am 3 credits away from finishing the traineeship<br />
<br />
The traineeship allowed me to consider a field in accelerator physics. I like that the professors are from different locations which give a different perspective and gives variety. The classes are condensed in a big time slot once a week which I like.<br />
<br />
The traineeship program changes things up from the regular Stony Brook classes, which do not give you specialized knowledge for your research. If you are interested in accelerators you need to have a background to understand the jargon and the technicalities and to be able to communicate. This program teaches you that. Again I like that the professors are from different locations which gives diversity and also networking potential.<br />

'''Arun Kingan'''<br />
<br />
[[Image:Kingan Arun.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
I am a masters student working with Axel Drees.<br />
<br />
My research is on analyzing the data from the PHENIX experiment on the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. Specifically I am studying proton-gold collisions and measuring the direct photon yield so as to better understand the onset of Quark Gluon Plasma (QGP) in heavy ion collisions. My day to day responsibilities consist of writing and fine tuning the analysis code.<br />
<br />
The traineeship provided a comprehensive education in accelerator science, which has clear applications to studying heavy ion collisions (i.e. the collision part). While it is unclear at the moment whether I will continue studying heavy ion collisions throughout my PhD and beyond, accelerator science also has applications in numerous other fields like material science, biology etc. I am sure in whatever area of research I end up in, the information I’ve learned through this traineeship will be invaluable.<br />
<br />
I will be finishing the program at the end of this semester<br />
<br />
I particularly enjoyed the introductory classes. They provided information over a broad scope, which I found to be the most interesting. Particularly the lessons on all the different applications of accelerators were the best.<br />
<br />
Accelerator science has applications in almost all areas of STEM. Wherever your personal research interests lie, participating in this program will give you a well-rounded education which will ultimately aid you in your research.<br />

<br />
I am a masters of science in instrumentation student.<br />
<br />
My research project involves the diffuse laser system for the sPHENIX TPC (Time Projection Chamber). The diffuse laser system will allow us to monitor dynamic space charge inside the TPC. My responsibilities lie with ensuring adequate light uniformity on the central membrane, and certain aspects of the manufacturing of the central membrane.<br />
<br />
I think it is important to understand the systems we are using on a large scale. I intend to work with a national lab, either after pursing a PhD, or directly after my MSI program.<br />
<br />
I have nearly completed the traineeship program requirements. My masters will continue for one more year.<br />
<br />
There are interesting classes to take and lots of people active in the field teaching us. I wish I had been able to get some more hands on experience though.<br />
<br />
It is an interesting and short program. It is funded by the US Dept. of Energy and financial support is a possibility for US citizens and permanent residents.<br />

<br />
I am a PhD student. I work with Dr. Y. Semertzidis, Dr. W. Morse and Dr. F. Meot<br />
<br />
My research project is to provide design and computational support in the proton EDM project, with a strong focus on spin dynamics in the storage ring and impact on the design and specifications regarding its optical components.<br />
<br />
By participating the Ernest Courant Traineeship program, I gain fruitful theoretical knowledge and hands-on simulation experience in the field of accelerator physics. The Ernest Courant Traineeship program improves my academic knowledge and boosts my technological skills towards my research career of accelerator physics. My career goal is to be a computational accelerator physicist.<br />
<br />
I have been in the program one semester (starting from Spring 2021)<br />
<br />
Besides the funding opportunities, I gain broad academic knowledge in accelerator physics from various courses (Stony Brook and USPAS), I also receive much useful information that would help me prepare to pursue my career goal.<br />
<br />
The Ernest Courant Traineeship program educates students to be accelerator physicists from the professional perspective. It helps students who are interested in accelerator physics explore their career in this area.<br />

<br />
I am a masters student.<br />
<br />
I am working on a research project at Brookhaven National Laboratory (BNL). The project is related to particle accelerator research. The research will be important for the current collider at BNL to increase its luminosity. My responsibilities are to operate, design and simulate the performance of the accelerator.<br />
<br />
My career goal is to become an Accelerator Physicist. The traineeship program gives me the opportunity to work with scientists around the world and gain many valuable experiences.<br />
<br />
I finished the program and joined Brookhaven National Laboratory as full-time this year.<br />
<br />
The best part of the traineeship program is that I can work with scientists around the world on a project which is closely relate to current physics research.<br />
<br />
I will highly recommend this program to other students. Students can work with people who are really good at this area. Particle accelerator research is also very important part of next generation physics research.</div>YichaoJinghttp://case.physics.stonybrook.edu/index.php?title=Careers_ASE_Irina_Petrushina&diff=3656Careers ASE Irina Petrushina2021-09-24T14:25:46Z<p>YichaoJing: </p>

<div>'''Dr. Irina Petrushina, PhD 2019'''<br />
<br />
[[Image:IrinaPetrushina_ATF.png|400px|Image: 1200 pixels|center]]<br />
<br />
<br />
What kind of career can a love of mathematics lead to? For Irina Petrushina it led to being a Research Scientist and Research Assistant Professor at Stony Brook University working on accelerator science and engineering. In high school she enjoyed languages and literature and played in the local theatre but her favorite subject by far was mathematics. This prompted her to seek education that would use a great deal of mathematics. Instead of working in pure math though she pursued career in physics as it uses mathematics to communicate the laws of nature, as she puts it.<br />
<br />
Irina initially studied at the National Research Nuclear University, Moscow Engineering Physics Institute, where she received the M.Sc. in 2013. When she was accepted to the NRNU MEPhI she was automatically assigned to the department of charged particle beams and accelerating devices. The more she worked on the design of superconducting accelerator structures the more she became interested in the field of accelerator physics in general. Internships at the German Electron Synchrotron Laboratory DESY and Fermi National Laboratory in Illinois allowed her to work alongside renowned accelerator physicists and experience the everyday life of a real scientist. This heavily influenced her to seek a graduate education in physics which she successfully did at Stony Brook University. She received the PhD in physics in 2019.<br />
<br />
As a Research Assistant Professor at Stony Brook University, Irina’s past and current work has focused on several aspects of accelerator physics which are of great importance to the advancement of accelerator science and medical and industrial applications of particle accelerators. She is now pursuing two substantially different, but closely intertwined aspects of modern accelerator physics: superconducting radiofrequency (SRF) photoinjectors and Laser Wake Field Accelerators (LWFA). While SRF technology remains the backbone of the so-called traditional or conventional accelerators, the rapidly evolving LWFA machines are starting to catch up to their elder siblings to produce high-brightness, high-quality beams. The overarching goal of her work is to fully explore the unique capabilities of the SRF gun, which is currently operating at nearby Brookhaven National Laboratory, and push its performance to the limit. <br />
<br />
Irina says working in physics is exciting, you are constantly being challenged, and never get a chance to be bored. Every day you learn something new or come up with a new solution to a challenging problem, and that can be very rewarding. At the same time, she wouldn’t say that it is simple, the scientific journey can be tough from time to time, and there will be moments, when you start questioning if this hard work really pays off. But if you really enjoy the challenge, if you like solving puzzles and making things happen, she feels physics is the right place for you. <br />
<br />
She also thinks that accelerator science is very unique in its way. Unlike the majority of disciplines in physics, there is no distinct separation between the experimental and theoretical sides. As an accelerator scientist, you get to work on a variety of aspects at the same time since it involves development of theoretical models, a variety of computer simulations, hands-on experiments, commissioning of the experimental setups and troubleshooting. Accelerator science is highly social as you get to work in a large group of physicists and engineers working towards the same goal.<br />
Asked about her most memorable parts of her education, Irina says that during her M.Sc., Prof. Ponomarenko taught a series of courses on metrology, tube amplifiers and transmission lines. She will never forget his impersonation of a dialog between a capacitor and an inductor. At Stony Brook she really enjoyed the electromagnetism lectures with Prof. Derek Teaney, Irina thinks that he is one of the most passionate professors she has ever seen. The way he builds the lectures and how actively he delivers the information is truly remarkable she says.<br />
<br />
Finally, Irina thinks that Long Island is a beautiful place to live. She says it is very rare to be in such a close proximity to both, the ocean beaches and the most dynamic and fascinating city in the world – New York city. Long Island offers a variety of activities with its beautiful wineries, amazing beaches and scenic villages out east. She feels that if you desire more action, New York city always has numerous attractions, museums, and events, which will never disappoint.<br />

<br />
Stony Brook University in collaboration with Brookhaven National Laboratory (BNL), Cornell University (CU) and FERMI National Accelerator Laboratory (FNAL) is establishing the Ernest Courant Traineeship in Accelerator Science & Engineering supported by a 5-year grant from the High Energy Office of the US Department of Energy. This novel program is named after eminent accelerator physicist, Ernest Courant, who lay the foundation of modern accelerator science. At SBU the traineeship is a part of the Center for Accelerator Physics and Education (CASE) – the http://case.physics.stonybrook.edu/index.php/Main_Page <br />
<br />
The main goal of the program is to train scientists and engineers in the field of accelerator sciences with a focus in the four areas identified as the DOE Mission Critical Workforce Needs in Accelerator Science and Engineering: (a) Physics of large accelerators and systems engineering; (b) Superconducting radiofrequency accelerator physics and engineering; (c) Radiofrequency power system engineering and (d) Cryogenic systems engineering (especially liquid helium systems).<br />

<br />
[[Image:Cosmotron.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
Particle accelerators are a futuristic technology that has many uses including for science, engineering, medicine and industrial applications. There are about 30,000 accelerators of all sizes in the world. Finding trained people who can understand, operate and engineer such systems is a problem. What is a particle accelerator? It is a circular or straight (linear) tube containing a vacuum in which atomic particles (i.e. electrons, protons or ions) can be accelerated to high speed using electric and/or magnetic fields. Research accelerators can be measured in miles. Many other accelerators are much smaller. What can the particle accelerators be used for? Some applications include: <br />

<br />
I am an MSI (masters of science in instrumentation) student working with Professor Thomas Hemmick.<br />
<br />
My research project is to help design the line laser calibration system for the Time Projection Chamber (TPC), which will be the central tracker of the sPHENIX detector at RHIC. A compact, steerable, ionizing laser calibration system will be used to provide a known track that allows us to study the evolving components of the distortion throughout the TPC. I have been working on simulations of this system so we can understand how to improve our calibration efforts and what the limits will be.<br />
<br />
I think receiving a certification specifically in accelerator science and engineering will be helpful in standing out in that field.<br />
<br />
I am about to be finished with the courses necessary for the traineeship but will be continuing research for at least a semester.<br />
<br />
The financial assistance has allowed me to focus more on what I am learning and my research, where otherwise I may not have been able to. This will leave me in a better place once I graduate. I think if a student is already interested in focusing on accelerator physics, there is no reason not to apply for the traineeship program; taking additional classes will prepare you better if this is what you want your career to be, and leaving graduate school with a certificate will help you find a job later.<br />

My project involves Plasma Wakefield Acceleration. The advancement of compact accelerators will have tremendous impact in the medical field. My responsibilities were to build a plasma Wakefield chamber, design and install components such as the differential pumping system, and the beam profile monitor system.<br />
<br />
Participating in the program trained me in specific classes that otherwise I would have not taken and makes me knowledgeable in the current developments in the field. It helps in learning the jargon and gives one a basis to start doing research where otherwise it might be difficult understanding even group meetings. It also allows one to interact and speak with specialists in the field. My career goal is to become a professor and research scientist working in a government lab in the accelerator field.<br />
<br />
I am 3 credits away from finishing the traineeship<br />
<br />
The traineeship allowed me to consider a field in accelerator physics. I like that the professors are from different locations which give a different perspective and gives variety. The classes are condensed in a big time slot once a week which I like.<br />
<br />
The traineeship program changes things up from the regular Stony Brook classes, which do not give you specialized knowledge for your research. If you are interested in accelerators you need to have a background to understand the jargon and the technicalities and to be able to communicate. This program teaches you that. Again I like that the professors are from different locations which gives diversity and also networking potential.<br />

<br />
[[Image:Kingan Arun.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
I am a masters student working with Axel Drees.<br />
<br />
My research is on analyzing the data from the PHENIX experiment on the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. Specifically I am studying proton-gold collisions and measuring the direct photon yield so as to better understand the onset of Quark Gluon Plasma (QGP) in heavy ion collisions. My day to day responsibilities consist of writing and fine tuning the analysis code.<br />
<br />
The traineeship provided a comprehensive education in accelerator science, which has clear applications to studying heavy ion collisions (i.e. the collision part). While it is unclear at the moment whether I will continue studying heavy ion collisions throughout my PhD and beyond, accelerator science also has applications in numerous other fields like material science, biology etc. I am sure in whatever area of research I end up in, the information I’ve learned through this traineeship will be invaluable.<br />
<br />
I will be finishing the program at the end of this semester<br />
<br />
I particularly enjoyed the introductory classes. They provided information over a broad scope, which I found to be the most interesting. Particularly the lessons on all the different applications of accelerators were the best.<br />
<br />
Accelerator science has applications in almost all areas of STEM. Wherever your personal research interests lie, participating in this program will give you a well-rounded education which will ultimately aid you in your research.<br />

I am a masters of science in instrumentation student.<br />
<br />
My research project involves the diffuse laser system for the sPHENIX TPC (Time Projection Chamber). The diffuse laser system will allow us to monitor dynamic space charge inside the TPC. My responsibilities lie with ensuring adequate light uniformity on the central membrane, and certain aspects of the manufacturing of the central membrane.<br />
<br />
I think it is important to understand the systems we are using on a large scale. I intend to work with a national lab, either after pursing a PhD, or directly after my MSI program.<br />
<br />
I have nearly completed the traineeship program requirements. My masters will continue for one more year.<br />
<br />
There are interesting classes to take and lots of people active in the field teaching us. I wish I had been able to get some more hands on experience though.<br />

<div>'''Dr. Rama Calaga, PhD 2016'''<br />
<br />
[[Image:Rama-pic2.jpg|300px|Image: 1200 pixels|center]]<br />
<br />
As a child in India, Rama Calaga was fascinated by physics and astronomy. He admits though that his perception of what physics was during his youth was more a fascination than reality. At Truman State in Missouri as an undergraduate student, he benefited from a close knit physics community of 7 professors and only 8 students. Rama thinks he was motivated to go to graduate school and study for a Ph.D thanks to all the professors at Truman who spent countless hours on the few physics students. He developed an interest in particle physics through a Research Experiences for Undergraduates (REU) program that is supported by the National Science Foundation. It introduced him to the practical world of experimental physics that is normally not obvious during undergraduate studies. Rama received his PhD in physics in 2016 from Stony Brook University.<br />
<br />
Today, Rama is an applied physicist specializing in accelerator physics at the particle physics lab CERN. It is hosted in Switzerland and France and is the largest particle collider in the world, built to probe the fundamental particles of nature and their interactions. Since 2016, he has worked primarily on superconducting radio-frequency cavities used for acceleration and deflection of particle beams. Along with a colleague at CERN almost 12 years ago, he proposed the use of special type of deflecting cavities (aka crab cavities) to increase the number of collisions at the Large Hadron Collider (LHC) by 70%, which is enormous. These cavities are now being built at CERN and in collaboration with the UK, US and Canada for its implementation in the LHC machine in 2026. Rama is excited to lead this project and see it through its implementation. <br />
<br />
He has been in the field for more than 15 years and each day there is new challenge and new ideas on a variety of topics. He has rich and diverse discussions with his colleagues, and it is a field in which he has grown to have many close friends who were first colleagues. He thinks that the field of physics is almost integrated into a daily life, it is not just another job. When he sees retired people eager to come back to CERN after the COVID restrictions to participate and contribute, it is really comforting to know that it is a lifelong adventure. There are not many fields one can say that of. <br />
<br />
Without considering only job opportunities (there are many), Rama firmly believe that physics and science in general offers a vast spectrum of academic opportunities for the curious mind. I believe we have only touched the surface of technological development and if one can project 100 years from now, the world will be different place. The foundation however is physics and science for this change to happen.<br />
<br />
When asked about his most positive experience he says that during his time at Stony Brook, “we rented a house with 5 other graduate students (3 in physics and 2 in music). They were from the U.S., Japan, India, and Australia it was really an enriching experience to pursue my doctoral studies in that environment. I certainly miss the campus experience and student life.” <br />
<br />
During his undergraduate studies, Rama worked at a summer camp in Missouri as a camp counselor for 2 summers. He did that to pay for his schooling, but that experience had a significant impact on his life and how he takes care of his kids today. <br />
<br />
When he started his pursuit of physics, Rama says he had a vague idea of physics, he thought knew everything but slowly along his studies he started to realize that he did not know much. His advice to students is be curious, ask, explore, and just don’t give up.<br />
<br />
On living near CERN, Rama says that Switzerland and France are wonderful. However, he does really miss the U.S. and New York in particular.</div>YichaoJinghttp://case.physics.stonybrook.edu/index.php?title=Ernest_courant_traineeship_main&diff=3646Ernest courant traineeship main2021-09-23T16:09:50Z<p>YichaoJing: /* Careers in Accelerator Science and Engineering */</p>

[[Image:Traineeship3.png|600px|Image: 1200 pixels|center]]<br />
<br />
Stony Brook University in collaboration with Brookhaven National Laboratory (BNL), Cornell University (CU) and FERMI National Accelerator Laboratory (FNAL) is establishing the Ernest Courant Traineeship in Accelerator Science & Engineering supported by a 5-year grant from the High Energy Office of the US Department of Energy. This novel program is named after eminent accelerator physicist, Ernest Courant, who lay the foundation of modern accelerator science. At SBU the traineeship is a part of the Center for Accelerator Physics and Education (CASE) – the http://case.physics.stonybrook.edu/index.php/Main_Page <br />
<br />
The main goal of the program is to train scientists and engineers in the field of accelerator sciences with a focus in the four areas identified as the DOE Mission Critical Workforce Needs in Accelerator Science and Engineering: (a) Physics of large accelerators and systems engineering; (b) Superconducting radiofrequency accelerator physics and engineering; (c) Radiofrequency power system engineering and (d) Cryogenic systems engineering (especially liquid helium systems).<br />

== '''Why Particle Accelerators?''' ==<br />
<br />
[[Image:Cosmotron.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
Particle accelerators are a futuristic technology that has many uses including for science, engineering, medicine and industrial applications. There are about 30,000 accelerators of all sizes in the world. Finding trained people who can understand, operate and engineer such systems is a problem. What is a particle accelerator? It is a circular or straight (linear) tube containing a vacuum in which atomic particles (i.e. electrons, protons or ions) can be accelerated to high speed using electric and/or magnetic fields. Research accelerators can be measured in miles. Many other accelerators are much smaller. What can the particle accelerators be used for? Some applications include: <br />

<br />
What kind of career can a love of mathematics lead to? For Irina Petrushina it led to being a Research Scientist and Research Assistant Professor at Stony Brook University working on accelerator science and engineering. In high school she enjoyed languages and literature and played in the local theatre but her favorite subject by far was mathematics. This prompted her to seek education that would use a great deal of mathematics. Instead of working in pure math though she pursued career in physics as it uses mathematics to communicate the laws of nature, as she puts it.<br />

<br />
I am an MSI (masters of science in instrumentation) student working with Professor Thomas Hemmick.<br />
<br />
My research project is to help design the line laser calibration system for the Time Projection Chamber (TPC), which will be the central tracker of the sPHENIX detector at RHIC. A compact, steerable, ionizing laser calibration system will be used to provide a known track that allows us to study the evolving components of the distortion throughout the TPC. I have been working on simulations of this system so we can understand how to improve our calibration efforts and what the limits will be.<br />
<br />
I think receiving a certification specifically in accelerator science and engineering will be helpful in standing out in that field.<br />
<br />
I am about to be finished with the courses necessary for the traineeship but will be continuing research for at least a semester.<br />
<br />
The financial assistance has allowed me to focus more on what I am learning and my research, where otherwise I may not have been able to. This will leave me in a better place once I graduate. I think if a student is already interested in focusing on accelerator physics, there is no reason not to apply for the traineeship program; taking additional classes will prepare you better if this is what you want your career to be, and leaving graduate school with a certificate will help you find a job later.<br />

<br />
[[Image:IrinaPetrushina_ATF.png|400px|Image: 1200 pixels|center]]<br />
<br />
<br />
What kind of career can a love of mathematics lead to? For Irina Petrushina it led to being a Research Scientist and Research Assistant Professor at Stony Brook University working on accelerator science and engineering. In high school she enjoyed languages and literature and played in the local theatre but her favorite subject by far was mathematics. This prompted her to seek education that would use a great deal of mathematics. Instead of working in pure math though she pursued career in physics as it uses mathematics to communicate the laws of nature, as she puts it.<br />
<br />
Irina initially studied at the National Research Nuclear University, Moscow Engineering Physics Institute, where she received the M.Sc. in 2013. When she was accepted to the NRNU MEPhI she was automatically assigned to the department of charged particle beams and accelerating devices. The more she worked on the design of superconducting accelerator structures the more she became interested in the field of accelerator physics in general. Internships at the German Electron Synchrotron Laboratory DESY and Fermi National Laboratory in Illinois allowed her to work alongside renowned accelerator physicists and experience the everyday life of a real scientist. This heavily influenced her to seek a graduate education in physics which she successfully did at Stony Brook University. She received the PhD in physics in 2019.<br />
<br />
As a Research Assistant Professor at Stony Brook University, Irina’s past and current work has focused on several aspects of accelerator physics which are of great importance to the advancement of accelerator science and medical and industrial applications of particle accelerators. She is now pursuing two substantially different, but closely intertwined aspects of modern accelerator physics: superconducting radiofrequency (SRF) photoinjectors and Laser Wake Field Accelerators (LWFA). While SRF technology remains the backbone of the so-called traditional or conventional accelerators, the rapidly evolving LWFA machines are starting to catch up to their elder siblings to produce high-brightness, high-quality beams. The overarching goal of her work is to fully explore the unique capabilities of the SRF gun, which is currently operating at nearby Brookhaven National Laboratory, and push its performance to the limit. <br />
<br />
Irina says working in physics is exciting, you are constantly being challenged, and never get a chance to be bored. Every day you learn something new or come up with a new solution to a challenging problem, and that can be very rewarding. At the same time, she wouldn’t say that it is simple, the scientific journey can be tough from time to time, and there will be moments, when you start questioning if this hard work really pays off. But if you really enjoy the challenge, if you like solving puzzles and making things happen, she feels physics is the right place for you. <br />
<br />
She also thinks that accelerator science is very unique in its way. Unlike the majority of disciplines in physics, there is no distinct separation between the experimental and theoretical sides. As an accelerator scientist, you get to work on a variety of aspects at the same time since it involves development of theoretical models, a variety of computer simulations, hands-on experiments, commissioning of the experimental setups and troubleshooting. Accelerator science is highly social as you get to work in a large group of physicists and engineers working towards the same goal.<br />
Asked about her most memorable parts of her education, Irina says that during her M.Sc., Prof. Ponomarenko taught a series of courses on metrology, tube amplifiers and transmission lines. She will never forget his impersonation of a dialog between a capacitor and an inductor. At Stony Brook she really enjoyed the electromagnetism lectures with Prof. Derek Teaney, Irina thinks that he is one of the most passionate professors she has ever seen. The way he builds the lectures and how actively he delivers the information is truly remarkable she says.<br />
<br />
Finally, Irina thinks that Long Island is a beautiful place to live. She says it is very rare to be in such a close proximity to both, the ocean beaches and the most dynamic and fascinating city in the world – New York city. Long Island offers a variety of activities with its beautiful wineries, amazing beaches and scenic villages out east. She feels that if you desire more action, New York city always has numerous attractions, museums, and events, which will never disappoint.<br />
<br />
Note: Dr. Irina Petrushina is the recipient of 2020 RHIC/AGS thesis award and also one of three physicists receiving the New York Academy of Sciences Blavatnik Award for Young Scientists.</div>YichaoJinghttp://case.physics.stonybrook.edu/index.php?title=File:PHY554_Lecture8_F2021.pdf&diff=3634File:PHY554 Lecture8 F2021.pdf2021-09-20T15:45:29Z<p>YichaoJing: </p>

10+ S.Y. Lee's and Edwards-Syphers' books are available in BNL library.<br />
<br />
== Course Description ==<br />
<br />
*Introduction to accelerator physics <br />You will have a glance into the history of accelerators and will learn about a variety of accelerators from electrostatic TV-tubes to gigantic atom and nuclear smashers. Basic figures of merit will be introduced (center of mass energy, luminosity, accelerating gradient, etc.) You will learn general principles behing linear accelerators and circular accelerators, their relative advantages and disadvantages.<br />
<br />
*Radio frequency cavities, linacs, superconducting RF accelerators <br />This part of the course will be dedicated to physics and technology of accelerating structures. You will learn basic principles of using radio frequency electromagnetic fields to accelerate particles to very high energies. Different types of accelerating structures will be introduced. You will also learn about brand new direction in linear accelerators – so-called energy recovery linacs. As many modern accelerators are based on superconducting RF (SRF) technlogy, you will learn fundamentals of the SRF accelerators and their advantages over conventional (normal conductoing) RF accelerators.<br />
<br />
*Linear transverse beam dynamics <br />This part of the course will be dedicated to detailed description of linear dynamics of particles in accelerators. You will learn about similarity of particles motion to an oscillator with time-dependent rigidity, matrix optics of various elements in accelerators, equation for beam envelopes and stability of periodic (circular) motion of the particles. Here you find a number of analogies with planetary motion, including oscillation of Earth’s moon. You will learn some “standards” of the accelerator physics – betatron tunes and beta-function and their importance in circular accelerators.<br />
<br />
*Nonlinear transverse beam dynamics <br />This lecture will open door in fascinating and never-ending elegance and complexity on nonlinear beam dynamics. You will learn about non-linear resonances, which may affect stability of the particles and about their location on the tune diagram. You will learn about chromatic (energy dependent) effects, use of non-linear elements to compensate them, and about problems created by introducing them. Some of traditional perturbation theory methods will be introduced during this lecture. <br />
<br />
*Longitudinal beam dynamics <br />If you were ever wondering why Saturn rings do not collapse into one large ball of rock under gravitational attraction – this where you will learn of the effect so-called negative mass in longitudinal motion of particles. You will also learn about so-called synchrotron oscillations, which are have a lot of similarity with pendulum motion. One more “tunes” to remember about - synchrotron tune.<br />
<br />
*Radiation effects <br />Charged particles going around an accelerator do radiate when their trajectory is bent – hence, there is entire range of topics arising from this fact. It goes from such effect as radiation damping of the particle oscillations, quantum excitation of such oscillation to the use of this extraordinary radiation as cutting-edge research tool. We will look both into positive (usefulness of synchrotron and FEL radiation) and negative (limiting the energy of electron storage rings) aspects of this natural phenomenon.<br />
<br />
*Accelerator applications <br />We will devote this part of the course to the discussion of variety of accelerator application, among which are accelerators for nuclear and particle physics, X-ray light sources, accelerators for medical uses, etc. You will also learn about future accelerators at the energy and intensity forntiers as well as about new methods of particle acceleration.<br />

<br />
==Learning Goals==<br />
<br />
Students who have completed this course should<br />
<br />
* Understand how various types of accelerators work and understand differences between them.<br />
* Have a general understanding of transverse and longitudinal beam dynamics in accelerators.<br />
* Have a general understanding of accelerating structures.<br />
* Understand major applications of accelerators and the recent new concepts.<br />
== Textbook and ''suggested materials''==<br />
<br />
Textbook is to be decided from the following:<br />
*Accelerator Physics, by S. Y. Lee<br />
*An Introduction to the Physics of High Energy Accelerators, by D. A. Edwards and M. J. Syphers<br />
*''Introduction To The Physics Of Particle Accelerators'', by Mario Conte and William W Mackay <br />
*''Particle Accelerator Physics'', by Helmut Wiedemann<br />
*''The Physics of Particle Accelerators: An Introduction'', by Klaus Wille and Jason McFall<br />
<br />
10+ S.Y. Lee's and Edwards-Syphers' books are available in BNL library.<br />
<br />
== Course Description ==<br />
<br />
*Introduction to accelerator physics <br />You will have a glance into the history of accelerators and will learn about a variety of accelerators from electrostatic TV-tubes to gigantic atom and nuclear smashers. Basic figures of merit will be introduced (center of mass energy, luminosity, accelerating gradient, etc.) You will learn general principles behing linear accelerators and circular accelerators, their relative advantages and disadvantages.<br />
<br />
*Radio frequency cavities, linacs, superconducting RF accelerators <br />This part of the course will be dedicated to physics and technology of accelerating structures. You will learn basic principles of using radio frequency electromagnetic fields to accelerate particles to very high energies. Different types of accelerating structures will be introduced. You will also learn about brand new direction in linear accelerators – so-called energy recovery linacs. As many modern accelerators are based on superconducting RF (SRF) technlogy, you will learn fundamentals of the SRF accelerators and their advantages over conventional (normal conductoing) RF accelerators.<br />
<br />
*Linear transverse beam dynamics <br />This part of the course will be dedicated to detailed description of linear dynamics of particles in accelerators. You will learn about similarity of particles motion to an oscillator with time-dependent rigidity, matrix optics of various elements in accelerators, equation for beam envelopes and stability of periodic (circular) motion of the particles. Here you find a number of analogies with planetary motion, including oscillation of Earth’s moon. You will learn some “standards” of the accelerator physics – betatron tunes and beta-function and their importance in circular accelerators.<br />
<br />
*Nonlinear transverse beam dynamics <br />This lecture will open door in fascinating and never-ending elegance and complexity on nonlinear beam dynamics. You will learn about non-linear resonances, which may affect stability of the particles and about their location on the tune diagram. You will learn about chromatic (energy dependent) effects, use of non-linear elements to compensate them, and about problems created by introducing them. Some of traditional perturbation theory methods will be introduced during this lecture. <br />
<br />
*Longitudinal beam dynamics <br />If you were ever wondering why Saturn rings do not collapse into one large ball of rock under gravitational attraction – this where you will learn of the effect so-called negative mass in longitudinal motion of particles. You will also learn about so-called synchrotron oscillations, which are have a lot of similarity with pendulum motion. One more “tunes” to remember about - synchrotron tune.<br />
<br />
*Radiation effects <br />Charged particles going around an accelerator do radiate when their trajectory is bent – hence, there is entire range of topics arising from this fact. It goes from such effect as radiation damping of the particle oscillations, quantum excitation of such oscillation to the use of this extraordinary radiation as cutting-edge research tool. We will look both into positive (usefulness of synchrotron and FEL radiation) and negative (limiting the energy of electron storage rings) aspects of this natural phenomenon.<br />
<br />
*Accelerator applications <br />We will devote this part of the course to the discussion of variety of accelerator application, among which are accelerators for nuclear and particle physics, X-ray light sources, accelerators for medical uses, etc. You will also learn about future accelerators at the energy and intensity forntiers as well as about new methods of particle acceleration.<br />

*An Introduction to the Physics of High Energy Accelerators, by D. A. Edwards and M. J. Syphers<br />
*''Introduction To The Physics Of Particle Accelerators'', by Mario Conte and William W Mackay <br />

10+ S.Y. Lee's and Edwards-Syphers' books are available in BNL library.<br />
<br />
== Course Description ==<br />
<br />
*Introduction to accelerator physics <br />You will have a glance into the history of accelerators and will learn about a variety of accelerators from electrostatic TV-tubes to gigantic atom and nuclear smashers. Basic figures of merit will be introduced (center of mass energy, luminosity, accelerating gradient, etc.) You will learn general principles behing linear accelerators and circular accelerators, their relative advantages and disadvantages.<br />
<br />
*Radio frequency cavities, linacs, superconducting RF accelerators <br />This part of the course will be dedicated to physics and technology of accelerating structures. You will learn basic principles of using radio frequency electromagnetic fields to accelerate particles to very high energies. Different types of accelerating structures will be introduced. You will also learn about brand new direction in linear accelerators – so-called energy recovery linacs. As many modern accelerators are based on superconducting RF (SRF) technlogy, you will learn fundamentals of the SRF accelerators and their advantages over conventional (normal conductoing) RF accelerators.<br />
<br />
*Linear transverse beam dynamics <br />This part of the course will be dedicated to detailed description of linear dynamics of particles in accelerators. You will learn about similarity of particles motion to an oscillator with time-dependent rigidity, matrix optics of various elements in accelerators, equation for beam envelopes and stability of periodic (circular) motion of the particles. Here you find a number of analogies with planetary motion, including oscillation of Earth’s moon. You will learn some “standards” of the accelerator physics – betatron tunes and beta-function and their importance in circular accelerators.<br />
<br />
*Nonlinear transverse beam dynamics <br />This lecture will open door in fascinating and never-ending elegance and complexity on nonlinear beam dynamics. You will learn about non-linear resonances, which may affect stability of the particles and about their location on the tune diagram. You will learn about chromatic (energy dependent) effects, use of non-linear elements to compensate them, and about problems created by introducing them. Some of traditional perturbation theory methods will be introduced during this lecture. <br />
<br />
*Longitudinal beam dynamics <br />If you were ever wondering why Saturn rings do not collapse into one large ball of rock under gravitational attraction – this where you will learn of the effect so-called negative mass in longitudinal motion of particles. You will also learn about so-called synchrotron oscillations, which are have a lot of similarity with pendulum motion. One more “tunes” to remember about - synchrotron tune.<br />
<br />
*Radiation effects <br />Charged particles going around an accelerator do radiate when their trajectory is bent – hence, there is entire range of topics arising from this fact. It goes from such effect as radiation damping of the particle oscillations, quantum excitation of such oscillation to the use of this extraordinary radiation as cutting-edge research tool. We will look both into positive (usefulness of synchrotron and FEL radiation) and negative (limiting the energy of electron storage rings) aspects of this natural phenomenon.<br />
<br />
*Accelerator applications <br />We will devote this part of the course to the discussion of variety of accelerator application, among which are accelerators for nuclear and particle physics, X-ray light sources, accelerators for medical uses, etc. You will also learn about future accelerators at the energy and intensity forntiers as well as about new methods of particle acceleration.<br />

You will learn some “standards” of the accelerator physics – betatron tunes and beta-function and their importance in circular accelerators.<br />
<br />
*Nonlinear transverse beam dynamics <br />This lecture will open door in fascinating and never-ending elegance and complexity on nonlinear beam dynamics. You will learn about non-linear resonances, which may affect stability of the particles and about their location on the tune diagram. You will learn about chromatic (energy dependent) effects, use of non-linear elements to compensate them, and about problems created by introducing them. Some of traditional perturbation theory methods will be introduced during this lecture. <br />
<br />
*Longitudinal beam dynamics <br />If you were ever wondering why Saturn rings do not collapse into one large ball of rock under gravitational attraction – this where you will learn of the effect so-called negative mass in longitudinal motion of particles. You will also learn about so-called synchrotron oscillations, which are have a lot of similarity with pendulum motion. One more “tunes” to remember about - synchrotron tune.<br />
<br />
*Radiation effects <br />Charged particles going around an accelerator do radiate when their trajectory is bent – hence, there is entire range of topics arising from this fact. It goes from such effect as radiation damping of the particle oscillations, quantum excitation of such oscillation to the use of this extraordinary radiation as cutting-edge research tool. We will look both into positive (usefulness of synchrotron and FEL radiation) and negative (limiting the energy of electron storage rings) aspects of this natural phenomenon.<br />
<br />
*Accelerator applications <br />We will devote this part of the course to the discussion of variety of accelerator application, among which are accelerators for nuclear and particle physics, X-ray light sources, accelerators for medical uses, etc. You will also learn about future accelerators at the energy and intensity forntiers as well as about new methods of particle acceleration.<br />

== Course Description ==<br />
<br />
*Introduction to accelerator physics <br />You will have a glance into the history of accelerators and will learn about a variety of accelerators from electrostatic TV-tubes to gigantic atom and nuclear smashers. Basic figures of merit will be introduced (center of mass energy, luminosity, accelerating gradient, etc.) You will learn general principles behing linear accelerators and circular accelerators, their relative advantages and disadvantages.<br />
<br />
*Radio frequency cavities, linacs, superconducting RF accelerators <br />This part of the course will be dedicated to physics and technology of accelerating structures. You will learn basic principles of using radio frequency electromagnetic fields to accelerate particles to very high energies. Different types of accelerating structures will be introduced. You will also learn about brand new direction in linear accelerators – so-called energy recovery linacs. As many modern accelerators are based on superconducting RF (SRF) technlogy, you will learn fundamentals of the SRF accelerators and their advantages over conventional (normal conductoing) RF accelerators.<br />
<br />
*Linear transverse beam dynamics <br />This part of the course will be dedicated to detailed description of linear dynamics of particles in accelerators. You will learn about similarity of particles motion to an oscillator with time-dependent rigidity, matrix optics of various elements in accelerators, equation for beam envelopes and stability of periodic (circular) motion of the particles. Here you find a number of analogies with planetary motion, including oscillation of Earth’s moon. You will learn some “standards” of the accelerator physics – betatron tunes and beta-function and their importance in circular accelerators.<br />

== Textbook and ''suggested materials''==<br />
<br />
Textbook is to be decided from the following:<br />
*Accelerator Physics, by S. Y. Lee<br />
*An Introduction to the Physics of High Energy Accelerators, by D. A. Edwards and M. J. Syphers<br />
*''Introduction To The Physics Of Particle Accelerators'', by Mario Conte and William W Mackay <br />
*''Particle Accelerator Physics'', by Helmut Wiedemann<br />
*''The Physics of Particle Accelerators: An Introduction'', by Klaus Wille and Jason McFall<br />
<br />
10+ S.Y. Lee's and Edwards-Syphers' books are available in BNL library.<br />
<br />
== Course Description ==<br />
<br />
*Introduction to accelerator physics <br />You will have a glance into the history of accelerators and will learn about a variety of accelerators from electrostatic TV-tubes to gigantic atom and nuclear smashers. Basic figures of merit will be introduced (center of mass energy, luminosity, accelerating gradient, etc.) You will learn general principles behing linear accelerators and circular accelerators, their relative advantages and disadvantages.<br />
<br />
*Radio frequency cavities, linacs, superconducting RF accelerators <br />This part of the course will be dedicated to physics and technology of accelerating structures. You will learn basic principles of using radio frequency electromagnetic fields to accelerate particles to very high energies. Different types of accelerating structures will be introduced. You will also learn about brand new direction in linear accelerators – so-called energy recovery linacs. As many modern accelerators are based on superconducting RF (SRF) technlogy, you will learn fundamentals of the SRF accelerators and their advantages over conventional (normal conductoing) RF accelerators.<br />
<br />
*Linear transverse beam dynamics <br />This part of the course will be dedicated to detailed description of linear dynamics of particles in accelerators. You will learn about similarity of particles motion to an oscillator with time-dependent rigidity, matrix optics of various elements in accelerators, equation for beam envelopes and stability of periodic (circular) motion of the particles. Here you find a number of analogies with planetary motion, including oscillation of Earth’s moon. You will learn some “standards” of the accelerator physics – betatron tunes and beta-function and their importance in circular accelerators.<br />
<br />
*Nonlinear transverse beam dynamics <br />This lecture will open door in fascinating and never-ending elegance and complexity on nonlinear beam dynamics. You will learn about non-linear resonances, which may affect stability of the particles and about their location on the tune diagram. You will learn about chromatic (energy dependent) effects, use of non-linear elements to compensate them, and about problems created by introducing them. Some of traditional perturbation theory methods will be introduced during this lecture. <br />
<br />
*Longitudinal beam dynamics <br />If you were ever wondering why Saturn rings do not collapse into one large ball of rock under gravitational attraction – this where you will learn of the effect so-called negative mass in longitudinal motion of particles. You will also learn about so-called synchrotron oscillations, which are have a lot of similarity with pendulum motion. One more “tunes” to remember about - synchrotron tune.<br />
<br />
*Radiation effects <br />Charged particles going around an accelerator do radiate when their trajectory is bent – hence, there is entire range of topics arising from this fact. It goes from such effect as radiation damping of the particle oscillations, quantum excitation of such oscillation to the use of this extraordinary radiation as cutting-edge research tool. We will look both into positive (usefulness of synchrotron and FEL radiation) and negative (limiting the energy of electron storage rings) aspects of this natural phenomenon.<br />
<br />
*Accelerator applications <br />We will devote this part of the course to the discussion of variety of accelerator application, among which are accelerators for nuclear and particle physics, X-ray light sources, accelerators for medical uses, etc. You will also learn about future accelerators at the energy and intensity forntiers as well as about new methods of particle acceleration.<br />

<div>== '''Ernest Courant Traineeship in Accelerator Science & Engineering''' ==<br />
<br />
[[Image:Traineeship3.png|600px|Image: 1200 pixels|center]]<br />
<br />
Stony Brook University in collaboration with Brookhaven National Laboratory (BNL), Cornell University (CU) and FERMI National Accelerator Laboratory (FNAL) is establishing the Ernest Courant Traineeship in Accelerator Science & Engineering supported by a 5-year grant from the High Energy Office of the US Department of Energy. This novel program is named after eminent accelerator physicist, Ernest Courant, who lay the foundation of modern accelerator science. At SBU the traineeship is a part of the Center for Accelerator Physics and Education (CASE) – the http://case.physics.stonybrook.edu/index.php/Main_Page <br />
<br />
The main goal of the program is to train scientists and engineers in the field of accelerator sciences with a focus in the four areas identified as the DOE Mission Critical Workforce Needs in Accelerator Science and Engineering: (a) Physics of large accelerators and systems engineering; (b) Superconducting radiofrequency accelerator physics and engineering; (c) Radiofrequency power system engineering and (d) Cryogenic systems engineering (especially liquid helium systems).<br />

== '''Why Particle Accelerators?''' ==<br />
<br />
[[Image:Cosmotron.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
Particle accelerators are a futuristic technology that has many uses including for science, engineering, medicine and industrial applications. There are about 30,000 accelerators of all sizes in the world. Finding trained people who can understand, operate and engineer such systems is a problem. What is a particle accelerator? It is a circular or straight (linear) tube containing a vacuum in which atomic particles (i.e. electrons, protons or ions) can be accelerated to high speed using electric and/or magnetic fields. Research accelerators can be measured in miles. Many other accelerators are much smaller. What can the particle accelerators be used for? Some applications include: <br />

'''Dr. Irina Petrushina''', PhD 2019<br />
<br />
[[Image:IrinaPetrushina.png|600px|Image: 1200 pixels|center]]<br />
<br />
What kind of career can a love of mathematics lead to? For Irina Petrushina it led to being a Research Scientist and Research Assistant Professor at Stony Brook University working on accelerator science and engineering. In high school she enjoyed languages and literature and played in the local theatre but her favorite subject by far was mathematics. This prompted her to seek education that would use a great deal of mathematics. Instead of working in pure math though she pursued career in physics as it uses mathematics to communicate the laws of nature, as she puts it.<br />

'''Dr. Rama Calaga''', PhD 2016<br />
<br />
[[Image:Rama-pic1.jpeg|400px|Image: 1200 pixels|center]]<br />
<br />
As a child in India, Rama Calaga was fascinated by physics and astronomy. He admits though that his perception of what physics was during his youth was more a fascination than reality. At Truman State in Missouri as an undergraduate student, he benefited from a close knit physics community of 7 professors and only 8 students. Rama thinks he was motivated to go to graduate school and study for a Ph.D thanks to all the professors at Truman who spent countless hours on the few physics students. He developed an interest in particle physics through a Research Experiences for Undergraduates (REU) program that is supported by the National Science Foundation. It introduced him to the practical world of experimental physics that is normally not obvious during undergraduate studies. Rama received his PhD in physics in 2016 from Stony Brook University.<br />

'''Kristina Finnelli'''<br />
<br />
[[Image:Finnelli Kristina.PNG|600px|Image: 1200 pixels|center]]<br />
<br />
I am an MSI (masters of science in instrumentation) student working with Professor Thomas Hemmick.<br />
<br />
My research project is to help design the line laser calibration system for the Time Projection Chamber (TPC), which will be the central tracker of the sPHENIX detector at RHIC. A compact, steerable, ionizing laser calibration system will be used to provide a known track that allows us to study the evolving components of the distortion throughout the TPC. I have been working on simulations of this system so we can understand how to improve our calibration efforts and what the limits will be.<br />
<br />
I think receiving a certification specifically in accelerator science and engineering will be helpful in standing out in that field.<br />
<br />
I am about to be finished with the courses necessary for the traineeship but will be continuing research for at least a semester.<br />
<br />
The financial assistance has allowed me to focus more on what I am learning and my research, where otherwise I may not have been able to. This will leave me in a better place once I graduate. I think if a student is already interested in focusing on accelerator physics, there is no reason not to apply for the traineeship program; taking additional classes will prepare you better if this is what you want your career to be, and leaving graduate school with a certificate will help you find a job later.<br />
<br />

'''Pietro Iapozzuto'''<br />
<br />
[[Image:Iapozzuto Pietro.jpeg|600px|Image: 1200 pixels|center]]<br />
<br />
I am pursuing a masters degree.<br />
<br />
My project involves Plasma Wakefield Acceleration. The advancement of compact accelerators will have tremendous impact in the medical field. My responsibilities were to build a plasma Wakefield chamber, design and install components such as the differential pumping system, and the beam profile monitor system.<br />
<br />
Participating in the program trained me in specific classes that otherwise I would have not taken and makes me knowledgeable in the current developments in the field. It helps in learning the jargon and gives one a basis to start doing research where otherwise it might be difficult understanding even group meetings. It also allows one to interact and speak with specialists in the field. My career goal is to become a professor and research scientist working in a government lab in the accelerator field.<br />
<br />
I am 3 credits away from finishing the traineeship<br />
<br />
The traineeship allowed me to consider a field in accelerator physics. I like that the professors are from different locations which give a different perspective and gives variety. The classes are condensed in a big time slot once a week which I like.<br />
<br />
The traineeship program changes things up from the regular Stony Brook classes, which do not give you specialized knowledge for your research. If you are interested in accelerators you need to have a background to understand the jargon and the technicalities and to be able to communicate. This program teaches you that. Again I like that the professors are from different locations which gives diversity and also networking potential.<br />

'''Arun Kingan'''<br />
<br />
[[Image:Kingan Arun.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
I am a masters student working with Axel Drees.<br />
<br />
My research is on analyzing the data from the PHENIX experiment on the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. Specifically I am studying proton-gold collisions and measuring the direct photon yield so as to better understand the onset of Quark Gluon Plasma (QGP) in heavy ion collisions. My day to day responsibilities consist of writing and fine tuning the analysis code.<br />
<br />
The traineeship provided a comprehensive education in accelerator science, which has clear applications to studying heavy ion collisions (i.e. the collision part). While it is unclear at the moment whether I will continue studying heavy ion collisions throughout my PhD and beyond, accelerator science also has applications in numerous other fields like material science, biology etc. I am sure in whatever area of research I end up in, the information I’ve learned through this traineeship will be invaluable.<br />
<br />
I will be finishing the program at the end of this semester<br />
<br />
I particularly enjoyed the introductory classes. They provided information over a broad scope, which I found to be the most interesting. Particularly the lessons on all the different applications of accelerators were the best.<br />
<br />
Accelerator science has applications in almost all areas of STEM. Wherever your personal research interests lie, participating in this program will give you a well-rounded education which will ultimately aid you in your research.<br />

<br />
[[Image:KN.png|600px|Image: 1200 pixels|center]]<br />
<br />
I am a masters of science in instrumentation student.<br />
<br />
My research project involves the diffuse laser system for the sPHENIX TPC (Time Projection Chamber). The diffuse laser system will allow us to monitor dynamic space charge inside the TPC. My responsibilities lie with ensuring adequate light uniformity on the central membrane, and certain aspects of the manufacturing of the central membrane.<br />
<br />
I think it is important to understand the systems we are using on a large scale. I intend to work with a national lab, either after pursing a PhD, or directly after my MSI program.<br />
<br />
I have nearly completed the traineeship program requirements. My masters will continue for one more year.<br />
<br />
There are interesting classes to take and lots of people active in the field teaching us. I wish I had been able to get some more hands on experience though.<br />
<br />
It is an interesting and short program. It is funded by the US Dept. of Energy and financial support is a possibility for US citizens and permanent residents.<br />

<br />
[[Image:LeeJonathan2.jpg|600px|Image: 1200 pixels|center]]<br />
<br />
I am a PhD student. I work with Dr. Y. Semertzidis, Dr. W. Morse and Dr. F. Meot<br />
<br />
My research project is to provide design and computational support in the proton EDM project, with a strong focus on spin dynamics in the storage ring and impact on the design and specifications regarding its optical components.<br />
<br />
By participating the Ernest Courant Traineeship program, I gain fruitful theoretical knowledge and hands-on simulation experience in the field of accelerator physics. The Ernest Courant Traineeship program improves my academic knowledge and boosts my technological skills towards my research career of accelerator physics. My career goal is to be a computational accelerator physicist.<br />
<br />
I have been in the program one semester (starting from Spring 2021)<br />
<br />
Besides the funding opportunities, I gain broad academic knowledge in accelerator physics from various courses (Stony Brook and USPAS), I also receive much useful information that would help me prepare to pursue my career goal.<br />
<br />
The Ernest Courant Traineeship program educates students to be accelerator physicists from the professional perspective. It helps students who are interested in accelerator physics explore their career in this area.<br />

<br />
I am a masters student.<br />
<br />
I am working on a research project at Brookhaven National Laboratory (BNL). The project is related to particle accelerator research. The research will be important for the current collider at BNL to increase its luminosity. My responsibilities are to operate, design and simulate the performance of the accelerator.<br />
<br />
My career goal is to become an Accelerator Physicist. The traineeship program gives me the opportunity to work with scientists around the world and gain many valuable experiences.<br />
<br />
I finished the program and joined Brookhaven National Laboratory as full-time this year.<br />
<br />
The best part of the traineeship program is that I can work with scientists around the world on a project which is closely relate to current physics research.<br />
<br />
I will highly recommend this program to other students. Students can work with people who are really good at this area. Particle accelerator research is also very important part of next generation physics research.</div>YichaoJing
