Collimation simulation of heavy-ion beams in the LHC — •Pascal Dominik Hermes^1,2, Roderik Bruce¹, and Stefano Redaelli¹ — ¹CERN, Geneva, Switzerland — ²Westfälische Wilhelms-Universität Münster, Germany

Simulations of the LHC collimation cleaning efficiency are crucial to understand the expected beam losses in superconducting magnets so that quenches can be avoided. Such simulations for heavy-ion beams require specialized software including ion-specific physics effects. A simulation approach combining ion fragmentation at a collimator with subsequent fragment tracking is presented. Simulated loss maps are compared to measured losses from LHC heavy-ion runs and possible improvements are discussed on the basis of the applied approximations. An outlook on the ion cleaning performance with future settings of the LHC collimation system is given.
