Understanding and possible mitigation strategies of the PS Booster BTV "like" impedances

In order to increase accelerator performance, striving for continuous improvement is needed. One of the priorities is to upgrade outdated devices. In the process of upgrading the devices, a series of studies on the impact on overall performance is needed. One of the major concerns is the effect on beam coupling impedance. This Summer Student Project report will investigate the effect of the new beam imaging system in the PS Booster regarding the beam coupling impedance. The report consists of an introduction related to the beam imaging system, and the status of preliminary BTV studies. After that, a numerical validation will be performed, which includes a convergence study and an Eigenmode and Wakefield solver comparison. After the numerical validation, a step-by-step approach is performed in order to understand the origins of the beam coupling impedance. The last step is related to beam coupling impedance mitigation, and some most promising solutions are shown. Additionally, some possible future work is outlined.
