Description

The existing code for particle scattering and tracking in collimation systems integrated in SixTrack, called K2, was migrated from the current software in FORTRAN, to a new Python/C interface integrated in the Xsuite tracking code that is being developed at CERN. This is an essential step towards a full integration of collimation studies using Xtrack, and will allow profiting from GPU computing advances and the BOINC volunteer computing network. Furthermore, several improvements to the functionality of the code were introduced, for example aperture interpolation for more precise longitudinal location of particle losses in a collimator. A thorough testing of the new implementation was performed, using as case studies various collimation layout configurations for the LHC Run 3 and HL-LHC. In this paper, the challenges are outlined and the first results are presented, including simulated loss maps which are compared to the reference results generated by SixTrack.
