Performance of LHCb Silicon Tracker Detector in the LHC

The LHCb experiment is designed to perform high-precision measurements of CP violation and search for New Physics using the enormous flux of beauty and charmed hadrons produced at the LHC. The LHCb detector is a single-arm spectrometer with excellent tracking and particle identification capabilities. The Silicon Tracker is part of the tracking system and measures very precisely the particle trajectories coming from the interaction point in the region of high occupancies around the beam axis. The LHCb Silicon Tracker covers a total sensitive area of about 12 m 2 using silicon micro-strip technology. This paper reports on the operation and performance of the Silicon Tracker during the Physics data taking at the LHC.
