The dynamics of ultra-compact and isochronous GeV energy FFAGS

Research output: Chapter in Book/Report/Conference proceedingConference contribution


The FFAG (Fixed-Field Alternating-Gradient) accelerator is a class of accelerators that comprises the best features of the cyclotron and the synchrotron, combining fixed magnetic fields with strong focusing gradients for stable, low-loss operation. Here, a new type of medium-energy 1 GeV isochronous (CW) FFAG has been developed in a racetrack layout that supports two opposing synchrotron-like straights, permitting both highgradient RF modules and efficient injection and extraction in a highly compact footprint. In this paper we present beam dynamic simulations for this compact racetrack FFAG, and compare the differences between an equivalent circular and racetrack configuration. A comparison of the FFAG dynamics with the 800-MeV (Daeδalus) cyclotron is briefly presented.
