TI - Shower Simulations for the CERN Proton Synchrotron Internal Dump and Comparison with Beam Loss Monitor Data J2 - Proc. of HB2023, Geneva, Switzerland, 09-13 October 2023 CY - Geneva, Switzerland T2 - ICFA Advanced Beam Dynamics Workshop on High-Intensity and High-Brightness Hadron Beams T3 - 68 LA - english AB - During the Long Shutdown 2 (LS2), two new internal dumps (TDIs) were installed and successfully put into operation in the CERN Proton Synchrotron (PS) to withstand the intense and bright beams produced for the High Luminosity LHC. TDIs serve as safety devices designed to rapidly enter the beam trajectory and stop the beam over multiple turns. Due to their design, the TDI only absorbs a fraction of the secondary particle shower produced by beam particles that impinge on it. Starting from impacts computed by multi-turn beam dynamics simulations, detailed shower simulations were performed with FLUKA to assess the radiation field’s impact on the downstream equipment, with a particular emphasis on the dose measured by Beam Loss Monitors. The numerical data obtained from the simulations are compared with the experimental data collected during PS operation.
