Recent beam tests of CMS MSGC tracker prototypes

The performance of MicroStrip Gas Chamber (MSGC) prototypes, developed for the barrel Tracking Detector of the Compact Muon Solenoid (CMS) experiment at LHC, has been extensively tested over the last years. We report the results from the most recent beam tests, which illustrate the standard performance of the detectors and the robustness of the MSGC technology in LHC-like beam conditions.
