Xcoll-BDSIM coupling for beam collimation

Xsuite is a comprehensive simulation toolkit for accelerator physics, with Xcoll serving as the dedicated module for collimation studies. These studies involve tracking particles through an accelerator and simulating their interactions with matter, taking into account non-linear elements and large betatron and off-momentum deviations. Particle-matter interactions can be modeled using an internal scattering model, Everest, or coupled to external codes. This paper presents the integration of Xcoll with the Geant4 libraries by utilizing the Beam Delivery Simulation (BDSIM) code. This coupling enables efficient tracking of diverse particle species through materials, along with realistic simulations of energy deposition and secondary particle production. The implementation is designed to be flexible, supporting the inclusion of detailed collimator geometries, beam-gas interactions, and crystal channeling effects.
