Introducing a semi-Gaussian mixture model for simulating multiple coulomb scattering in RF-track
/ Stechauner, Bernd (CERN ; TU Vienna) ; Frühwirth, Rudolf (Vienna, OAW) ; Latina, Andrea (CERN) ; Schulte, Daniel (CERN) ; Schieck, Jochen (Vienna, OAW)
Within the context of a design study of a LINAC for ionization cooling, this paper presents the result of incorporating a scattering model in RF-Track (v2.1) for charged particles heavier than electrons. This inclusion enables simulations for applications like ionization cooling channels for muon colliders. [...]

The Beam Coupling Impedance (BCI) is a crucial aspect in the realm of accelerator physics, as it describes the electromagnetic interactions between charged particle beams and the accelerator structure. The measurement and quantification of BCI is an essential requirement to assess and mitigate its impact, particularly when introducing new components or addressing problems within existing devices.
