Performance of the Barrel Muon System with Missing - Superlayers
نویسندگان
چکیده
Performance studies of the CMS barrel muon system carried out at INFN Bologna are described in detail. The expected muon momentum resolution and trigger efficiency are calculated for different configurations of the measuring superlayers. The emphasis here is not on the absolute response, but rather on the comparison of the various configurations. ) On leave from INRNE, Sofia, Bulgaria

Wide-range Precision Alignment for the Gem Muon System
The GEM muon system [1] is designed to achieve high momentum resolution by precisely measuring muon trajectories at three equidistant superlayers separated by a long lever arm in a large magnetized volume. In order to retain the desired precision at high momentum (i.e. ∆pt/pt ≈ 5% for the barrel detector at pt = 500 GeV/c), the muon system must determine the net 3-point sagitta of a muon track ...
