Abstract

The cleaning efficiency requirements in the LHC are beyond the requirements at other circular colliders. The achievable ideal cleaning efficiency in the LHC is presented for the improved LHC collimation system. The longitudinal distribution of proton losses is evaluated with a realistic aperture model of the LHC. The results from simplified tracking studies are compared to simulations with complete physics and error models. Possibilities for beambased optimization of collimator settings are described.
