Muon Track Reconstruction Efficiency of ME1/1 Dubna Prototype in the Integrated Test

The aim of this note is to study a track reconstruction efficiency of muons detected with six-layer CSC and its distortion by electromagnetic secondaries induced by the high energy muon passed through a hadron calorimeter. Experimental data taken in the Integrated Test of CMS endcap detector prototypes were used for analysis

The Muons Registration Efficiency of the CMS ECAL Preshower in the Integrated Test

The Muon registration efficiency of the Preshower was estimated from experimental data of the Integrated Test of the module, that is a prototype of the CMS Endcap detector. In the work it is shown that the muon registration efficiency of the preshower plane is 93% for the muon particles with the energy from 100 to 300 GeV in 3 Tesla axial magnetic field. It was mainly defined by the noise value of the electronics devices-AMPLEX SICAL chips. The muons energy loss distribution in the preshower planes was investigated. A mathematical method was proposed to describe the distribution of the energy losses taking into account the intrinsic noise of the electronics devices. A comparison of the experimental data with the simulation results was made

Increasing muon-track reconstruction efficiency in ME1/1 Dubna prototype for the CMS/LHC

The aim of this work is to increase the efficiency of muon track reconstruction and estimate a number of electromagnetic secondaries in the muon detector for experimental data from the Integrated Test set-up, the prototype of CMS endcap segment. The experimental data have shown that the high energy beam of muons (100-300 GeV) produces 20-25% of events with electromagnetic secondaries. Though the muon coordinate measurements were distorted by secondaries, we have managed to obtain a high efficiency (>or=92%) of muon track reconstruction. The investigation has been performed at the Laboratory of Computing Techniques and Automation and the Laboratory of Particle Physics. (4 refs)
