Optimisation of the layout of the LHC collimation system

Machine related backgrounds arise mainly either from the halo that accompanies the core beam or from accidental losses due to individual events. Particles at large displacements from the core can impact on beam-line apertures, including collimators, and then exit the beam-pipe downstream. Looking towards the initial LHC upgrades, an ESR project at RHUL will look into an optimisation of the layout of the LHC collimation system to minimize beam related backgrounds in the ATLAS detector at CERN and also look into optimizing the LHC injection region to minimize activation in that region. The material interactions will be simulated using BDSIM and will then be cross-checked with FLUKA simulations performed at CERN.


The multi-turn tracking will be performed using SIXTRACK and a suitable interface provided to streamline the transfer of large-amplitude particles to BDSIM. The beam loss monitors will be modeled in Geant4 and included within the BDSIM package; in this way an accurate modeling of the response of the LHC to beam losses will be obtained.
