Results of the Muon Flux and Spectrum Measurement for the SHiP Experiment — •Stefan Bieschke, Caren Hagner, and Daniel Bick — Universität Hamburg, Institut für Experimentalphysik, Luruper Chaussee 149, 22761 Hamburg

The SHiP experiment is a proposed beam dump experiment dedicated for the Search for Hidden Particles. Utilizing the 400 GeV proton beam of CERN’s SPS at a high intensity, it can explore physics beyond the standard model at the intensity frontier. A large number of protons on target, however, is accompanied by a huge amount of muons emerging from the target which would enter the detector’s acceptance and render the observation of hidden particle decays impossible. A magnetic shield is foreseen to deflect the muons away from the detector, which is optimized using a particle simulation. Due to the complex interactions in a dense proton beam dump, an experimental verification of the simulation was considered necessary. In 2018, a replica of the proton target was used in the SPS beam to verify the simulated flux and spectrum. The experimental setup and the results of the data analysis will be presented.
