Description
The core of the CMS experiment is a three layers pixel detector. Installed in 2008 the CMS pixel system is essential for track seeding and reconstruction of secondary vertexes. The Pixel detector was designed for a peak luminosity of 1E34 cm-2s-1. The presentation will summarize the operational experience of the first three years of collisions at the LHC. We will present the measured performance evolution as the Instantaneous luminosity delivered increased by several order of magnitude including dynamic data-losses, efficiency and resolution. The focus of the presentation will be on operational parameters, online calibrations and a overview of the challenges encountered to present.
