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

Le résumé fourni par la source

The muon registration efficiency of the preshower was estimated from experimental data of the integrated test of the module, that is a prototype of CMS Endcap detector. 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.
