“…The CMS RPCs have been extensively tested at the production sites and their physics performance was studied [3,5]. During 2006, a small fraction of the RPC system was calibrated and operated [9]. In both cases, it was found that 95 % of the maximum plateau efficiency is reached at an effective voltage of 9.6 kV, corresponding to an average applied voltage of 9.2 kV for the pressure conditions in the CMS cavern.…”

“…For each slice we have a different cluster size distribution and the random number, corresponding to the cluster size, is generated from the distribution. All the distributions have been obtained from the experimental data, using an algorithm explained in [18]. An example of such a distribution is presented on fig.…”

The Resistive Plate Chamber (RPC) muon subsystem contributes significantly to the formation of the trigger decision and reconstruction of the muon trajectory parameters. Simulation of the RPC response is a crucial part of the entire CMS Monte Carlo software and directly influences the final physical results. An algorithm based on the parametrization of RPC efficiency, noise, cluster size and timing for every strip has been developed. Experimental data obtained from cosmic and proton-proton collisions at √ s = 7 TeV have been used for determination of the parameters. A dedicated validation procedure has been developed. A good agreement between the simulated and experimental data has been achieved.

“…The detector efficiency estimation was achieved by means of two different methods: "linear segment extrapolation" [2] and "stand alone extrapolation". The "segment extrapolation" method makes use of the muon track segments provided by the Drift Tube (DT) detector and performs linear extrapolation to the adiacent RPC in the same station.…”

During the period July-September 2009 the CERN CMS experiment [1] undertook a long cosmic data taking period, called Cosmic Run At Four Tesla (CRAFT09). Several millions of cosmic muon events were collected to achieve first detector calibration, synchronization and performance study. CMS RPC system was carefully monitored and its performance were evaluated. Dedicated tools in order to manage the workflow of data analysis and algorithms to measure the detector and trigger efficiency were implemented.
