Status of the CMS silicon strip tracker

Abstract

The CMS silicon strip tracker with its more than 15000 silicon modules and about 200 m2 of active silicon area will resume operation after three years of Long Shutdown 2 in the Spring of 2022. We present the status of the detector before the start of the LHC Run 3 data taking. The performance of the detector during the Run 2 data taking is presented including the signal-to-noise ratio, fraction of bad components in the detector, hit efficiency, and single hit resolution. We discuss projections of the detector performance during Run 3. In addition the change of detector parameters with increasing radiation damage is reviewed.
