Performance Simulation of the Cathode Strip Chambers for CMS End Cap Muon System

A model has been considered of the Cathode Strip Chamber (CSC) exposed to the muon stream of high intensity (70 Hz/cm2) originating in the crossing point of beams of the LHC collider. To reproduce the experimental conditions, the intensity of the muon stream in our model had the impulse structure of 40MHz rate. Complete simulation of registration process from initial ionization to the final signals was performed for muons that cross the 6-layers trapezoidal CSC. The anode and cathode current signals were used for evaluation of the hits and for simulation of the cathode pulse shape in the Switch Capacity Array (SCA). The Anode and Cathode Local Charged Tracks as well as the 1-level trigger solutions were generated for reconstruction of the tracks and for approximate evaluation of their space and time coordinates by means of the logic approved for CMS End Cap Muon System. More exactly, the time and spatial coordinates of detected muons have been determined from fitting of the SCA information.
