An extensive aging study of bakelite Resistive Plate Chambers
نویسندگان
چکیده
We present recent results of an extensive aging test, performed at the CERN Gamma Irradiation Facility, on two bakelite Resistive Plate Chambers (RPC) detectors. With a method based on a model describing the behavior of an RPC exposed to a large particle flux, we have periodically measured the electrode resistivity r of the two detectors over 3 years. We observed a large increase of r with time, from initial values of about 10 O cm to more than 200 10 O cm: A corresponding degradation of the RPC rate capability, from about 3 kHz=cm to less than 200 Hz=cm; was observed. The reversibility of the process, using a humid gas mixture, has also been studied. r 2003 Elsevier B.V. All rights reserved.

Final results from an extensive ageing test of bakelite Resistive Plate Chambers
We present the final results of an extensive aging test, performed at the CERN Gamma Irradiation Facility on two bakelite Resistive Plate Chambers (RPC) detectors. With a method based on a model describing the behaviour of an RPC under high particle flux conditions, we have periodically measured the electrode resistivity r of the two RPC prototypes over 3 years. We observed a large spontaneous ...
متن کاملStudy of the Resistive Plate Chambers for the ALICE Dimuon Arm
The trigger system for the ALICE Dimuon Arm will be based on Resistive Plate Chambers. A RPC prototype, with electrodes made of low resistivity bakelite (ρ ∼ 3·109Ωcm) has been tested both at the SPS and at the GIF. The results for operation in streamer mode are presented here.
متن کاملBeam Test Results on Resistive Plate Chambers for the CMS Experiment
Resistive Plate Chambers were tested in a muon and a pion beam to study the performances at different running conditions. Results on a first chamber built without the linseed oil treatment of the bakelite surfaces are presented together with an evaluation of the local effects due the spacers. These results are extrapolated to the conditions expected at LHC.
متن کاملAging tests and chemical analysis of Resistive Plate Chambers for the trigger of the ALICE dimuon arm
Resistive Plate Chambers operated in streamer mode have been chosen as trigger detectors for the forward dimuon spectrometer of the ALICE experiment. During tests performed at CERN PS, small size prototypes with low-resistivity bakelite electrodes and with a strongly quenched gas mixture have shown the required rate capability, tracking and timing properties. Present efforts are devoted to the ...
متن کاملResistive Plate Chamber Performance in the BaBar IFR System
The BaBar Collaboration has operated a system covering over 2000 m with resistive plate chambers for nearly three years. The chambers are constructed of bakelite sheets separated by 2 mm. The inner surfaces are coated with linseed oil. This system provides muon and neutral hadron detection for BaBar. Installation and commissioning were completed in 1998, and operation began mid-1999. While init...
