Abstract :
Inside the CMS detector11The Compact Myon Solenoid Technical Proposal, CERN/LHCC 9438 LHCC/pp1(1994).
ed particles are measured precisely with layers of low-occupancy silicon detectors and Micro Strip Gas Chambers (MSGCs) with pitches of 50 and 200 μm, respectively. Low occupancy is achieved by a high granularity of 3×106 channels for silicon detectors and 11×106 for MSGCs. For the CMS forward tracker we tested a closed MSGC module with wedge-shaped strip patterns on 300 μm DESAG26322High resistivity boro-silicate glass manufactured by Deutsche Spezialglas AG.
substrates produced by OPTIMASK. Using a 100 GeV μ-beam at CERN we investigated the behaviour of this MSGC module foreseen for four wedge-shaped substrates, 512 strips each.
