Abstract
The CMS Silicon Strip Tracker with its more than 15000 silicon modules and 200 m$^2$ of active silicon area has been running together with the other subsystems of CMS for several years. We present the performance of the detector in the LHC Run 2 data taking. Results for signal-to-noise, hit efficiency and single hit resolution will be presented. We review the behavior of the system when running at beyond-design instantaneous luminosity and describe challenges observed under these conditions. The evolution of detector parameters under the influence of radiation damage are presented and compared to simulations.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
