The COMPASS experiment at CERN uses silicon microstrip detectors for beam definition and vertex reconstruction. Since 2009, the detectors are operated at cryogenic temperatures to minimize radiation damage. The development of a new, modular phase separator for the liquid nitrogen cooling system of the detector modules as well as the construction of a water cooling system for the frontend electronics of these detectors are presented. In addition, results of the alignment studies for the 2012 Primakoff run are shown.
