Cryogenic Silicon Detectors for the COMPASS Experiment at CERN

In 2002 the COMPASS experiment at CERN has started to take physics data. The fixed target experiment at the SPS uses muon and hadron beams of very high intensity to investigate the structure of the nucleon. For beam definition and small angle tracking silicon microstrip detectors are used. This article describes the current design and the performance of the cryogenic cooling system of these detectors as well as the further development which is underway.
