Tests of the Silicon Strip Sensors for the CMS Tracker

The Compact Muon Solenoid (CMS) is one of the experiments at the Large Hadron Collider (LHC) currently under construction at CERN. Its inner tracking system consists of the worldʹs largest Silicon Strip Tracker which implements around 25 000 silicon sensors covering an active area of 206 m2. S collaboration developed a detailed testing scheme in order to ensure the functionality of all these sensors for the full LHC lifetime. The measurements performed on the sensors will be presented. Selected results from these measurements and a comparison with the data from the suppliers will be shown.
