Offline calibrations and performance of the CMS pixel detector

Offline calibrations and performance of the CMS pixel detector

The CMS pixel detector, divided into barrel and endcap subdetectors, has 66 million pixels. We present the offline algorithms and results for the gain/pedestal and Lorentz angle calibrations. The determination of the optimal clock delay settings with initial data is described. The expected detector...

Beschreibung
Zusammenfassung:The CMS pixel detector, divided into barrel and endcap subdetectors, has 66 million pixels. We present the offline algorithms and results for the gain/pedestal and Lorentz angle calibrations. The determination of the optimal clock delay settings with initial data is described. The expected detector performance from Monte Carlo simulations is compared to the real performance in 7 TeV proton–proton collisions.
