INTEGRATED SIMULATION TOOLS FOR COLLIMATION CLEANING IN HL-LHC

The Large Hadron Collideris designed to accommodate an unprecedented stored beam energy of 362 MJ in the nominalconfigurationandaboutthedoubleinthehigh-luminosity upgradeHL-LHCthatispresentlyunderstudy. Thisrequires an ecient collimation system to protect the superconductingmagnetsfromquenches. Duringthedesign, itistherefore very important to accurately predict the expected beam loss distributions and cleaning eciency. For this purpose, there are several ongoing eorts in improving the existing simulation tools or developing new ones. This paper gives a brief overview and status of the dierent available codes.
