Description
Studies of radiation damage to the CMS Pixel Detector during LHC
running are presented. Leakage current and depletion voltage are
monitored with increasing fluence. Methods for addressing the
challenges of these measurements in the context of ongoing detector
operations are discussed. These include the derivation of depletion
voltage from hit efficiencies, the measurement of silicon temperature
and extrapolation of current as a function thereof, and determination
of the total fluence from LHC luminosity. The results allow for
validation of existing radiation damage models of radiation damage and
an improved understanding of the anticipated lifetime of the Pixel
Detector.
