Description
Due to the large amount of energy stored in the LHC ring, cleaning of
the beam halo is necessary in order to avoid quenches of the LHC
superconducting magnets.
We review the mechanisms of multi-turn beam losses and design
parameters of the LHC collimation system, and present the cleaning
performance for various beam lifetimes scenarios, both at injection
and top energy.
Results of tracking simulations after cleaning process are presented:
inefficiency curves and longitudinal/transvere loss maps, with and
without machine imperfections.
