Integrated Simulation Tools for Collimation Cleaning in HL-LHC

The Large Hadron Collider is designed to accommodate
an unprecedented stored beam energy of 362 MJ in the nominal
configuration and about the double in the high-luminosity
upgrade HL-LHC that is presently under study. This requires
an efficient collimation system to protect the superconducting
magnets from quenches. During the design, it is therefore
very important to accurately predict the expected beam loss
distributions and cleaning efficiency. For this purpose, there
are several ongoing efforts in improving the existing simulation
tools or developing new ones. This paper gives a brief
overview and status of the different available codes.
