Operational experience with the CMS pixel detector

The CMS pixel detector consists of 15840 readout chips, containing a total of almost 66 million pixels. In this paper, I describe the preparation for the first data-taking with LHC beams, in which the performance of the readout chips was optimized using a suite of calibrations. The detector threshol...

description The CMS pixel detector consists of 15840 readout chips, containing a total of almost 66 million pixels. In this paper, I describe the preparation for the first data-taking with LHC beams, in which the performance of the readout chips was optimized using a suite of calibrations. The detector thresholds have been adjusted to be less than 3000 electrons, and the effect of timing on the thresholds has been studied. After the arrival of LHC beam in December of 2009, the timing of the detector was optim ized to achieve maximum efficiency, using both online and offline analysis. I will also discuss the challenges presented by beam backgrounds.
