GAS Studies

The RPC performance dependence on several factors like the flow rate, quality of the gas mixture, environment etc. Some simulation studies (CDF) for flow distribution of gas inside the RPC is done which show that, there are some “dead zones”, where the gas does not reach some pockets inside the RPC. The nozzle positions dependence is also observed in the simulation studies. The flow resistors...
Resistive Plate Chamber (RPC) detectors are widely employed in the muon trigger systems of three experiments at the CERN Large Hadron Collider (LHC) thanks to their excellent time resolution. The LHC RPC systems are operated under gas recirculation to reduce operation cost and greenhouse gas emissions since their gas mixture is based on C2H2F4, which has a high global warning potential....
All types of RPC are operating in very strong and homogeneous electric fields from 50 to 160 kV/cm and gas mixtures at atmospheric pressure. The width of the gas gaps vary between 140 µm and 2 mm. Especially crucial is the selection of gas mixtures to prevent permanent gas discharges and aging of the electrodes.
For a deeper understanding of the gas discharge under RPC conditions a high...
Resistive Plate Chambers are the gaseous detectors and uses gas as their active medium for the detection of charge particles. Glass based resistive plate chambers of size 2m X 2m, operated in avalanche mode will be used as an active detector element at INO-ICAL experiment. In order to fulfill the physics goal, about 29,000 RPCs will be used for 20 long years. The quality and purity of the gas...
