Description
Beam dynamics studies, and in particular detailed macroparticle simulations, are challenging for high-energy hadron synchrotrons due to the large number of circulating bunches. The High-Luminosity Large Hadron Collider (HL-LHC) will accelerate beams with twice the LHC design intensity. It will also feature additional installations such as the crab cavities, which increase the total impedance of the accelerator. In the longitudinal plane, the baseline HL-LHC scenario will push the beam parameters close to the stability limit. This contribution presents particle tracking studies evaluating the coupled-bunch motion during the injection plateau, where bunch trains are initially mismatched and receive energy kicks after injection. The impact of the crab cavity higher-order-mode impedances on the beam stability threshold with operational beam parameters is studied and compared to the latest measurements and semi-analytical results.
