Performance of the COMPASS Trigger — •Benjamin Moritz Veit — Institut fuer Kernphysik Universitaet Mainz

The Common Muon Proton Apparatus for Structure and Spectroscopy or short COMPASS is running since 2001 in different setups to study the hadron structure and hadron spectroscopy with high intensity muon and hadron beams.
For the 2016/2017 run a liquid hydrogen target with a 160 Gev/c polarised muon beam is used to extract the Generalized Parton Distributions (GPDs) from beam and spin cross section differences. Thus measurements with positively and negatively charged muons were performed. Stable working conditions for both beam polarities during the whole data taking of ∼200 days are mandatory for the extraction of cross section differences. The performance and stability of the 2016 GPD Trigger setup in comparison to the previous runs will be presented.
