Description

Studies are ongoing at CERN's Super Proton Synchrotron (SPS) to understand the origin and distribution of observed beam losses. The existing equipment in the machine allows for dedicated measurements to identify bottleneck regions with higher losses. A well-suited and accurate simulation model of the SPS is indispensable to be able to study the impact of underlying beam dynamics on the loss distribution. This paper reviews the current state of the SPS model in Xsuite for loss simulations. The aperture model has recently been improved, and additional features can be enabled on demand, such as collimators and lattice non-linearities. Furthermore, the impact of the beam sagitta in bending magnets can be represented by introducing aperture offsets. This paper presents the results of the current setup, compares them to dedicated measurements, and outlines the next steps for further improvements.
