CMS NOTE 1997 / 003 CMS Note
Abstract A 2 mm gas gap Resistive Plate Chamber with bakelite plates has been operated in avalanche mode under a 137Cs source irradiation. We report on measurements of the efficiency in cosmic rays detection and of the charge developed in the gap, performed for two different gas mixtures: the first containing a high percentage of environmental friendly ”freon” C2H2F4; the second one having a hi...
متن کاملon CMS information server CMS NOTE 1997 / 004 CMS Note The Compact Muon Solenoid Experiment
Some properties of a 90% C2H2F4 gas mixture, used to operate resistive plate chambers in avalanche mode, are determined by comparing the experimental results with the prediction of simple analytical calculations. The fast charge distribution of the signal induced on pick-up electrodes is reproduced by means of a Monte Carlo simulation of the avalanche development. In addition predictions for a ...

متن کاملCMS information server CMS NOTE 1997 / 043 CMS Note The Compact
The effect of external as well as internal bremsstrahlung radiation in H ! ZZ ! 4e channel is studied in full detector simulation. A method is proposed for external and internal bremsstrahlung recovery, allowing us to use 95% of electrons within j E=pgen 1 j 0.2. It is shown that traditional E=p and isolation cuts can be implemented with 90% efficiency, but that precise mass reconstruction is a...
متن کاملThe Rpc System for the Cms Experiment at Lhc 1 Cms Detector 2 Cms Muon Trigger
The CMS experiment designed for Large Hadron Collider is brieey described. An idea of a muon trigger based on RPC is presented. This talk focuses on the requirements on RPC as the trigger detectors for the CMS. We discuss the required chamber's parformance and segmentation. Current design of the system fulllling these requirements is presented. Its expected trigger performances are given. The a...
