CMS Silicon Strip Tracker Operations and Performance
Gehalten von DI Dr. Michael Hoch am 03.11.2010 bei IEEE2010: 2010 Nuclear Science Symposium, Medical Imaging conference and RTDS workshop, 30 Oct-6 Nov 2010, Knoxville, TN (United States)
The CMS silicon strip tracker is the largest silicon detector ever built with almost 10 million readout channels and an active area of close to 200 m^2. Its more than 15,000 individual silicon modules are powered by almost 1000 power supply modules and produce more than 60 kW of power while operating at low temperatures. Results from the successful operation of the tracker at the first LHC collisions at 0.9, 2.4, and 7 TeV, including environmental control, calibration, detector performance, and monitoring, are discussed. The detector performance is excellent, manifested in a nearly 100% functional tracker with high single hit efficiency, good S/N performance, and high quality track resolution. This is made possible by a fine-grained calibration process and a monitoring of all important quantities for the detector performance during different stages of the operation.
