COMPASS is a high-energy physics experiment at the Super Proton Synchrotron (SPS) at CERN in Geneva, Switzerland. The purpose of this experiment is the study of hadron structure and hadron spectroscopy with high intensity muon and hadron beams.
About 240 physicists from 11 countries and 28 institutions work in COMPASS, which has been the largest running experiment at CERN until the start of the Large Hadron Collider (LHC). It has also been a pioneer in adopting new detector and readout technologies such as GEM and MicroMega tracking detectors.
The experimental setup has a fixed-target geometry and features a two-level magnetic spectrometer with calorimeters and particle identification in both levels.
