Operation of the CMS Strip Detector

Abstract

The CMS Silicon Strip Tracker is the largest silicon detector ever built. The high precision measurement of the track hit position, over a large radius range, determines the unprecedented performance of CMS tracking. The operational experience matured on this very complex detector up to the first half of 2011 and the current status are described here, including the powering system, cooling and the back-end electronics. The commissioning sequence to calibrate the detector is illustrated and results on the detector performance are presented.

Performance of the CMS silicon tracker

“…The CMS Tracker has a fully analog readout and can therefore measure the track specific ionization loss, a powerful observable for particle identification, as discussed in [4] [14].…”
