Talk Overview
LHC Collimation Review 30/5/2013 E.Skordis
• IR7 modeling• SixTrack (beam tracking) and FLUKA
(interaction and secondary shower) interplay• 4TeV (February 2013 quench test) and 6.5TeV
(post-LS1 operation)Warm Section SimulationCold Section Simulation (peak power (dose) in the
SC coils, BLM pattern)
IR7 FLUKA geometryBeam 2 (internal)• Long Straight Section

• Left Dispersion Suppressor + Arch up to cell 14
BLM response factors• Significant differences in BLM response depending on
many parameters:
• Correspondence between monitor signal (what we see) and relevant quantities (what we care about, e.g. energy deposition in the coils) not universal
Position of the BLM Geometry surrounding the BLM Crosstalk shower
