Ion Beam Transport Glossary
Brief definitions to beam transport terms used in an accelerator. We will try to add one or two links, typically to more complete definitions and/or more specific information on the particular devices students will use in the Lab Course.
- Electrostatic Triplet
- A set of three electrostatic quadrupoles. A triplet/dipole combination (perhaps with a pair of bender plates) can be anastigmatic.
- Inflection Magnet
- This author does not know why it is traditional in the near-barrier nuclear physics community to refer to the dipole after the ion source as the inflection magnet. This magnet provides mass selection.
- Magnetic Quadrupole
- A magnet with 4 poles, alternating N-S-N-S. By itself, an element which focuses weakly in one plane while defocusing in the perpendicular plane.
- Magnetic Steerer
- Simple beam optical element using small dipole fields to steer the ion beam. Usually made without a core.
- Strong Focusing
- The use of 2 or more magnetic quadrupoles in an alternating gradient, used to focus the ion beam in accelerators. We at SBU and BNL are proud of the contribution that Ernest Courant made to the discovery and application of this principle.
