Abstract :
The CMS Silicon Strip Tracker (SST) needs to be precisely calibrated in order to correctly interpret and reconstruct the events recorded from the detector, ensuring that the SST performance fully meets the physics research program of the CMS experiment. Calibration constants may be derived within several workflows, from promptly reconstructed events with particles as well as from commissioning events gathered just before the acquisition of physics runs. These calibration procedures have been exercised in summer 2008 and 2009, when the CMS detector has been commissioned using cosmic muons with and without magnetic field. In this paper the reconstruction strategies, the calibration procedures and the detector performance results from the latest CMS operation are described.
