Description
The purpose of LHCb is to search for indirect evidence of new physics in decays of heavy hadrons. The LHCb detector is a single-arm forward spectrometer with precise silicon-strip detectors in the regions with highest particle occupancies. The non-uniform exposure of the LHCb sensors makes it an ideal laboratory to study radiation damage effects in silicon detectors.
Dedicated scans are regularly taken, which allow a precise measurement of the charge collection efficiency (CCE) and the calibration of the operational voltages.
The measured evolution of the effective depletion voltage $V_{depl}$ will be shown, and compared with the Hamburg model prediction. The overall performance of the LHCb silicon tracker will be presented.
