| Abstract | In the framework of the LHC Injector Upgrade project, a newinternal dump for the CERN Proton Synchrotron (PS) ring has beendesigned, installed, and successfully commissioned. This device isdesigned to move rapidly into the beam and stop charged particlesover several thousand turns to provide protection to PS hardwareagainst beam-induced damage. Due to its design, the internal dumpabsorbs only a fraction of the secondary particles shower producedby the beam particles that impinge on it. The performance of thedump should ensure efficient use throughout the PS energy range,i.e. from injection at 2 GeV (kinetic energy) to flat top at26 GeV (total energy). This paper presents comprehensive numericalsimulations that combine advanced beam dynamics and beam-matterinteraction codes to analyse the behaviour of stopped or scatteredparticles. Based on the impacts computed by multi-turn beam dynamicssimulations, detailed shower simulations with FLUKA wereperformed to assess the impact of the radiation field on downstreamequipment, with a particular emphasis on the dose measured by BeamLoss Monitors. The results of these numerical simulations arecompared with the data collected during the routine operation of thePS and its internal dump. |
