Status of SixTrack with collimation

In this paper, we review the functionality and status of the collimation version of SixTrack. It is a simulation tool that contains both an accurate magnetic tracking of an ensemble of particles, as well as a model for particle-matter interaction inside collimators, in order to model the efficiency of a proton collimation system. We summarize recent upgrades and improvements and we review also a benchmark with measured data before finally discussing plans for future development.
