The COMPASS trigger for Drell-Yan Measurement 2018 — •Benjamin Veit — for the COMPASS Collaboration, Institut für Kernphysik, Mainz, Germany

In 2018 the COMPASS experiment measures double-muon-production in the reaction of negative pions of 190 GeV/c with a polarized ammonia target. This process is called Drell-Yan process. The final state consists of two oppositely charged muons and a hadronic state. The hadrons and remaining beam pions are removed by an absorber directly behind the target, the remaining muon pairs are detected in the double stage COMPASS spectrometer. For a symmetric acceptance for positive and negative muons, the muon trigger system has to be modified. The setup and monitoring of the COMPASS muon trigger system for the 2018 run will be presented.
