The course is intended for graduate students who want to gain knowledge about contemporary particle accelerators and their applications. During the semester, students will learn the basics on accelerator physics principles and accelerator operation as well have the unique opportunity to gain “hands-on” experience on an operational accelerator. Students will also learn advanced computational techniques in order to model and analyze their experiments.
The course will cover a wide array of the measurements and manipulations that are needed for beam dynamics studies. Upon completion, students are expected to understand the basic principles and relations of beam dynamics, many of which they will have experimentally verified. Furthermore, they will have gained experience in measurement techniques and analysis of experimental observations.
While emphasis will be given on experiments, it will also offer exposure to the latest accelerator computer simulation techniques.
Several major topics will be covered during the semester:
- source physics
- magnet measurements
- optical imaging and processing using both fast and integrating devices
- phase space mapping and emittance measurement
- longitudinal dynamics and energy spread, beam control
Overall, students will be exposed to a number of state-of-the-art diagnostics and experimental techniques.
A total of 7 experiments will be conducted focusing in three different research areas: Beam control and focusing, beam diagnostic techniques, and electromagnetic phenomena on particle beams. The students will have hands-on experience on an operational accelerator and will be responsible for setting up the equipment, obtaining their own measurements, and analyzing the data. For same experiments students will be asked to model the experiments and compare results with measurements. Three lectures will be given – one for each group of experiments. During the lecture the students will learn the basics on beam diagnostic and imaging methods, beam manipulation techniques as well as the basic theory on electromagnetic phenomena on particle beans. A fourth lecture will be devoted on advanced computation techniques for analyzing results in accelerator physics. The primary simulation codes for this class will be ASTRA and ELEGANT while some experience with MATLAB, or Mathematica will be useful. During the semester, students will prepare two reports (each at different group areas). The content should include: 1) A background section which describes the experiment and explain the objectives, 2) A summary of measurements taken in the lab, 3) detailed data analysis and discussion, and 4) conclusion remarks. In addition, at the end of semester each student will be asked to prepare a presentation covering an experiment from a different group of experiments from any of the reports
LOCATION: The first class will be at Stony Brook University, Chemistry Building 124 All remaining classes will be at Brookhaven National Laboratory (BNL), Building 820
IMPORTANT: When you arrive at BNL's main gate, please inform the guard you are attending the Advanced Accelerator Laboratory Course at the ATF. You may be requested to check in at the nearby security trailer or research support building (Bldg. 400), where proper visitor identification may be required . We highly recommend that you will arrive no later than 3:30 pm during your first time for registration.
