This device is meant to move rapidly into the beam and stop charged particles over several turns to provide protection to the PS hardware against beam-induced damage. The performance of the dump should ensure efficient use throughout the PS energy range, i.e. from injection at 2 GeV (kinetic energy) to flat top at 26 GeV (total energy). In this paper, detailed numerical simulations are presented, carried out with a combination of sophisticated beam dynamics and beam-matter interaction codes, assessing the behaviour of stopped or scattered particles. The results of these numerical simulations are compared with the data collected during the routine operation of the PS and its internal dump.}}, }
