Silicon Microstrip Detectors for the COMPASS Experiment* — •Robert Wagner, Boris Grube, Rita De Masi, Igor Konorov, Stephan Paul, and Michael Wiesmann — TU München, Physik-Department E18, James-Franck-Straße, 85747 Garching, Germany

The fixed target experiment COMPASS at the CERN SPS started taking data in 2001. As part of its tracking system, double-sided silicon microstrip detectors have been commissioned in the target region of the experiment. The readout system is based on the APV25 chip and a low-noise ADC module performing zero suppression. The detector design and setup is described. While operation at cryogenic temperatures is planned in 2002, for the 2001 run emphasis was still set on investigating the detectors’ properties. The system has been operated in the COMPASS high-intensity muon beam, where the noise performance, the ADC data reduction algorithms, the time resolution and further detector parameters could be studied. *This project is supported by the BMBF and the Maier-Leibnitz-Labor, Garching
