Megjegyzések:	In the Compact Muon Solenoid (CMS) Experiment, muon detection in the forward direction isaccomplished by Endcap Muon system which is comprised of 468 Cathode Strip Chambers (CSCs). Thesedetectors identify muons, provide a fast muon trigger, and give a measurement of the muon trajectory.In this paper, we present results of the detector performance analyses based on the data collectedduring the Magnet Test and Cosmic Challenge (MTCC) exercise conducted by the CMS experiment in2006. About 8% of the full system (36CSCs) operated for a few months and collected cosmic ray data.We show that CMSCSCs identify two-dimensional trigger primitives with a 99.9% efficiency. Thesesegments, found by the CSC electronics after the passing of a muon through the chambers, are the inputinformation for the Level-1 muon trigger and, also, are a necessary condition for chambers to be readout by the Data Acquisition System (DAQ). The spatial resolution per chamber is measured to be around1002200mm. In contrast to the earlier studies based on a total detector area typically limited to 0:01m2(efficiency) and 3m2(resolution), results presented in this report were obtained for many installed CSCsoperating in situ over an area of 20m2(efficiency) and 60m2(spatial resolution).
