SPS-to-LHC Transfer Lines Loss Map Generation Using PyCollimate

The Transfer Lines (TL) linking the Super Proton Synchrotron (SPS) to the Large Hadron Collider (LHC) are both equipped with a complete collimation system to protect the LHC against mis-steered beams. During the setting up of these collimators, their gaps are positioned to nominal values and the phase-space coverage of the whole system is checked using a manual validation procedure. In order to perform this setting-up more efficiently and more reliably, the simulated loss maps of the TLs will be used to validate the collimator positions and settings. In this paper, the simulation procedure for the generation of TL loss maps is described, and a detailed overview of the new scattering routine (pycollimate) is given. Finally, the results of simulations benchmark with another scattering routine are presented.
