The performance of irradiated CMS silicon mirco-strip detector modules

The central tracking system of the Compact Muon Solenoid (CMS) experiment will be entirely buil in silicon technology. The majority of the CMS tracker consists of silicon micro-strip detectors which have to be operated in the harsh environment of the Large Hadron Collider (LHC) over a period of ten years. The expected equivalent fluences range from a low of 0.7 x 10^14 n_1MeV/cm^2 at the outermost layers of the tracker, to a high of 1.6 x 10^14 n_1MeV/cm^2 at the layers closest to the interaction region. In this paper, results from studies of irradiatied CMS silicon detector modules are presented.
