Abstract:
In general, the time of flight of a charged particle in an accelerator will
depend on the particle's transverse amplitude. This effect can become
important in machines with large transverse emittances, such as muon
accelerators. We will describe the effect, its physical origin, and the
circumstances where it becomes important. We will then demonstrate that the
effect is directly related to chromaticity. We will describe the effect on the
longitudinal dynamics in various circumstances, including linacs and fixed
field alternating gradient accelerators (FFAGs). We will describe methods for
correcting the effect, particularly in FFAGs.
