Cosmic ray tests of double-gap resistive plate chambers for the CMS experiment

The new Time-of-Flight (TOF) subsystem for STAR at RHIC will have 3840 6-pad Multigap Resistive Plate Chambers (MRPC) distributed over 120 trays. Each tray contains 192 channels and three types of electronics cards: “TINO”, “TDIG” and “TCPU”. Every 30 trays send data to a “THUB” card that interfaces to STAR trigger and transmits data over fiber to a STAR DAQ fiber receiver. TINO contains analog front end electronics based on the CERN/LAA NINO custom IC. TDIG digitizes the data using the CERN HPTDC ASIC. TCPU formats and buffers the digital information. A cosmic ray test system comprised of three plastic scintillators, 4 MRPC modules, and TOF prototype electronics is used to determine the timing resolution to be achieved for the entire TOF system. Overall timing resolution of 80 – 110 ps has been achieved.

Intense Research

Resistive Plate Chambers (RPC) have been chosen as dedicated trigger detectors for the CMS experiment at the LHC. The expected severe operating conditions have required an intense research and development activity on these detectors over the past years. Experimental results on overall performance of large chambers, rate capability, ageing and photon sensitity are reviewed. In all of these tests the detector has proven to achieve good enough performance for successful use at the LHC.

Data Analysis System

The CMS experiment was completely assembled in the fall of 2008 after a decade of design, construction and installation. During the last two years, cosmic ray data were taken on a regular basis. These data have enabled CMS to align the detector components, both spatially and temporally. Initial use of muons has also established the relative alignment of the CMS tracking and muon systems. In addition, the CMS calorimetry has been crosschecked with test beam data, thus providing an initial energy calibration of CMS calorimetry to about 5%. The CMS magnet has been powered and field mapped. The trigger and data acquisition systems have been installed and run at full speed. The tiered data analysis system has been exercised at full design bandwidth for Tier0, Tier1 and Tier2 sites. Monte Carlo simulation of the CMS detector has been constructed at a detailed geometric level and has been tuned to test beam and other production data to provide a realistic model of the CMS detector prior to first collisions.
