The Physics and Technology of Cyclotrons


Felix Marti, Michigan State University

Purpose and Audience
The purpose of this course is to introduce the students to the physics and technology of cyclotrons. This course is suitable for senior-level physics undergraduates or students from other fields interested in learning the physics of cyclotron design and operation. This course can also provide an improved background to engineers and technicians working with cyclotrons. The basic principles and definitions of beam dynamics will be emphasized and used to analyze experimental observations.

Courses in Electromagnetism and Classical Mechanics.

Instructional Method
This course includes a series of lectures and problem discussion sessions. Problem sets will be assigned that will be expected to be completed outside of scheduled class sessions. We plan to make extensive use of orbit tracking programs to illustrate the beam dynamics issues.

Course Content
Introduction and origin of the cyclotron. Magnetic field and isochronous condition. Central region, electric and magnetic focusing. Main acceleration region, resonances, focusing, space charge, extraction methods. Ion sources and injection systems. Magnets, compact and separated sectors, room temperature and superconducting. RF and beam diagnostics. Examples of state of the art cyclotrons and future trends.

Reading Requirements
(to be provided by the USPAS) Reprints from several papers and notes.

Credit Requirements
Students will be evaluated based on performance: final exam (40 % of final grade), homework assignments (60 % of final grade).
