The simulation of magnets for CERN particle accelerators is an essential part of the design process of new units, the analysis of the functionality of old ones, and even to guide the identification of magnet faults. One such application is the analysis of the future H- injection system for the Proton Synchrotron Booster (PSB). In order to inject H- ions into the accelerator, strip them of their electrons and combine them with proton bunches already circulating, a series of chicane magnets has been designed. Due to space constraints, these chicane magnets must be placed within the fringe field of main bending magnets of the ring. The coupling of these magnets has been assessed using Opera 3D’s TOSCA solver, and the particle tracking feature. The resulting trajectory and field maps provide an indication of how this interaction can be accounted for. In addition, the results can be used as a tool for the assessment of the beam behaviour, and for identifying and correcting sources of beam loss during commissioning.
