Abstract
In 2002 the Compass experiment at Cern has started to take first 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 requirements which are set by the physics program of Compass for these detectors and the ways they were met, amongst which the operation at a temperature around 130 K (Lazarus effect) is the most prominent. Measurements at low temperatures as well as first results from the operation at room temperature in the Compass physics run 2002 are presented.
