Abstract

Monte Carlo simulations are required to accurately eval- uate beam losses and secondary radiation in particle accel- erators and beamlines. Detailed Computer-Aided-Design (CAD) geometries are critical to provide the most realistic distribution of material masses but increase the model com- plexity and often lead to code duplication. Beam Delivery Simulation (BDSIM) and the Python package PYG4OMETRY enable handling such accelerator models within a single, simplified workflow to run complete simulations of primary and secondary particle tracking and interactions with matter using Geant4. Replacing geometries of straight magnets is trivial in BDSIM. However, for curved magnets, the proce- dure is significantly more complicated and time-consuming for the user. Additional capabilities have therefore been de- veloped to facilitate the design of arbitrary bent magnets by associating externally modelled geometries to the magnet poles, yoke, and beampipe. Individual field descriptions can
be associated with the yoke and vacuum pipe separately to provide fine-grained control of the magnet model. The im- plementation of these new features is described in detail and applied to the modelling of the CERN Proton Synchrotron (PS) combined function magnets.
