摘要：

The work presented here describes the characterization of double layer, bakelite RPCs for the end-cap region of the "Compact Muon Solenoid" experiment at LHC, which were built, assembled and tested in India before their dispatch to CERN in 2008. These detectors consist of eight of RE*/2 and two of RE*/3 type geometry for the CMS. The RE*/2 detectors had gas-gaps made at KODEL, Korea, and the two RE*/3 detectors had gas-gaps from GT, Italy, supplied to us from the CMS spare pool. We discuss the efficiency, leakage currents, strip profile and cluster size of these detectors as has been evaluated with the cosmic hodoscope at ISR Laboratory, CERN, where all the eight RE*/2 RPCs qualified for the cosmic tests, thereby ascertaining the QA/QC procedures followed during assembly at RPC Laboratory, Nuclear Physics Division, BARC, Mumbai, which is also geared up for the RPC upscope for CMS.
