Description
We will discuss the early Run II performance of the CMS Pixel and Strip Tracker, with the detector operating cold for the first time. The startup conditions at 13 TeV for both subdetectors will be summarised, including specifics for 50ns and 25ns operations and improvements in calibrations which were developed during 2013 and 2014. The impact of the Tracker alignment based on cosmic and collision data-taking will also be discussed together with the detector performance at high pileup.
