The performance of the CMS muon detector in proton-proton collisions at √s= 7 TeV at the LHC
(2013)Journal of InstrumentationThe performance of all subsystems of the CMS muon detector has been studied by using a sample of proton-proton collision data at √s = 7 TeV collected at the LHC in 2010 that corresponds to an integrated luminosity of approximately 40 pb-1. The measured distributions of the major operational parameters of the drift tube (DT), cathode strip chamber (CSC), and resistive plate chamber (RPC) systems met the design specifications. The spatial ...Journal Article -
Energy calibration and resolution of the CMS electromagnetic calorimeter in pp collisions at √s = 7 TeV
(2013)Journal of InstrumentationThe energy calibration and resolution of the electromagnetic calorimeter (ECAL) of the CMS detector have been determined using proton-proton collision data from LHC operation in 2010 and 2011 at a centre-of-mass energy of √s = 7 TeV with integrated luminosities of about 5\fbinv. Crucial aspects of detector operation, such as the environmental stability, alignment, and synchronization, are presented. The in-situ calibration procedures are ...Journal Article
