The ion injectors of the CERN accelerator chain, in particular the SuperProton Synchrotron (SPS) and the Low Energy Ion Ring (LEIR), operate in astrong Space Charge (SC) and Intra-Beam Scattering (IBS) regime, which candegrade beam quality. Optimizing the ion beam performance requires thus tostudy the interplay of these two effects in tracking simulations byincorporating both SC and IBS effects interleaved with lattice non-linearities.In this respect, the kinetic theory approach of treating IBS effects has beendeployed. A new, modified approach has been introduced using the formalism ofthe Bjorken and Mtingwa model and the complete integrals of the second kind forfaster numerical evaluation. This IBS kick is implemented in PyORBIT andextensive benchmarking cases against analytical models are shown. Results ofcombined space charge and intra-beam scattering simulations for the SPS andLEIR are presented and compared with observations from beam measurements.
