The High Luminosity Large Hadron Collider (HL-LHC) and the LIU (LHC-Injection Upgrade) projects at CERN call for increasing beam brightness and intensity. In this scenario, some critical machine components have to be redesigned and rebuilt. Due to the increase in beam intensity, minimizing the electromagnetic interaction between the beam and the device is a key design driver because this can lead to beam instabilities and excessive thermo-mechanical loading of devices. In this context, this study presents the results of the analysis on the thermal and mechanical effects induced by beam impedance heating for the new proton synchrotron (PS) internal dump.
