We present simulations of magnetic fields, particle tracking and other aspects of a novel compact design for an iRCMS (ion rapid cycling medical synchrotron), which is presently under development. The present design is based on previous work [1]. The dipole arcs make use of combined-function magnets and a small aperture beam pipe to minimize cost and footprint. The field overlap between the combined-function bending magnets is such that accurate simulations require treating the entire girder as a single magnetic unit. We describe and present results from simulations using a detailed field map and the Zgoubi code [2] to study this machine. All recent modeling results will be summarized.
