Study of the effect of water vapor on a resistive plate chamber with glass electrodes
نویسندگان
چکیده
We studied the effects of water vapor on the efficiencies of resistive plate chambers with glass electrodes, operated in the streamer mode. With moisture in the chamber gas that has freon as a component (water vapor B1000 ppm), a decrease in the efficiency (B20%) has been observed after operating for a period of several weeks to a few months. From our study, the cause of the efficiency decrease was identified as a change on the cathode surface. In addition, a recovery method was found: flushing for 1 day with argon bubbled through water containing X3% ammonia, followed by a few weeks of training with dry gas. r 2001 Elsevier Science B.V.

Study of the effect of water vapor on a glass RPC with and without freon
We studied the effects of freon (fluoride) in a chamber gas on damaging the glass electrodes combined with water vapor (1000–2000 ppm). The damage was observed only for the combination of freon and water vapor. r 2003 Elsevier Science B.V. All rights reserved.
متن کاملAFM pictures of the surfaces of glass RPC electrodes damaged by water vapor contamination
We present surface pictures of the damaged electrodes from the Glass Resistive Plate Chambers (GRPCs) taken by an Atomic Force Microscope (AFM). For the test, a set of chambers were operated with freon mixed gas (damaged) and freonless gas (not damaged), contaminated with 1000 ∼ 2000 ppm of water vapor. In the AFM pictures, clear differences in damage are seen between the electrodes in the cham...
متن کاملThickness Dependence of Sensitivity in Thin Film Tin Oxide Gas Sensors Deposited by Vapor Pyrolysis
Transparent SnO2 thin films were deposited on porcelain substrates using a chemical vapor deposition technique based on the hydrolysis of SnCl4 at elevated temperatures. A reduced pressure self-contained evaporation chamber was designed for the process where the pyrolysis of SnCl4 at the presence of water vapor was carried out. Resistive gas sensors were fabricated by providing ohmic contacts o...
متن کاملObservation of light from resistive plate chambers
Electrically induced signals and light emissions from Restrictive Plate Chamber (RPC) are simultaneously measured using a glass RPC with transparent high-voltage planes, operating in the streamer mode. With one exception, good correspondence is seen in between the electrical and optical signals in every aspect: signal shapes, pulse heights, timing and afterpulses. The one exception is a possibl...
