Collimation cleaning for HL-LHC optics scenarios with error models

The upgrade of the LHC collimation system in view of the High-Luminosity upgrade of the Large Hadron Collider (LHC) foresees, amongst other scenarios, local collimation in the Dispersion Suppressors (DS) of IR7. Layouts have been worked out which rely on using stronger and short bending dipoles to f...

description The upgrade of the LHC collimation system in view of the High-Luminosity upgrade of the Large Hadron Collider (LHC) foresees, amongst other scenarios, local collimation in the Dispersion Suppressors (DS) of IR7. Layouts have been worked out which rely on using stronger and short bending dipoles to free space for a collimator in the cold DS. In this paper, the effectiveness of the proposed layouts is studied with different imperfection models such as collimator alignment, jaw tilt and surface errors, gap errors and aperture imperfections. The effect of local DS collimation on the global losses around the ring is also addressed for different optics configurations.
