Description
The computer code Zgoubi calculates charged particle trajectories in electric and
magnetic fields. It allows the study of complex sequences of optical elements such as
dipoles, quadrupoles, arbitrary multipoles, RF cavities and radial sector FFAG
magnets. A new optical element - spiral sector FFAG magnet – has been recently
installed in order to perform ray-tracing simulations in such a structure. This paper
describes how this method for modeling of the magnetic field in spiral scaling FFAG
magnets has been developped. We then describe first simulation results for spiral
FFAG lattices in the frame of the French RACCAM project which has to study and build
a FFAG magnet for protontherapy.
