New results from an extensive aging test on bakelite Resistive Plate
نویسندگان
چکیده
We present recent results of an extensive aging test, performed at the CERN Gamma Irradiation Facility on two single–gap RPC prototypes, developed for the LHCb Muon System. With a method based on a model describing the behaviour of an RPC under high particle flux conditions, we have periodically measured the electrode resistance R of the two RPC prototypes over three years: we observe a large spontaneous increase of R with time, from the initial value of about 2 MΩ to more than 250 MΩ. A corresponding degradation of the RPC rate capabilities, from more than 3 kHz/cm 2 to less than 0.15 kHz/cm 2 is also found.

متن کاملA new surface treatment for the prototype RPCs of the BESIII spectrometer
The prototype resistive plate chambers (RPCs) for the BESIII spectrometer were constructed by using resistive electrodes made from a special type of phenolic paper laminates developed by us. The surface quality of these laminates is superior to other bakelite plates that have been used to construct RPCs elsewhere. A method for adjusting the resistivety of these laminates was also developed. Ext...
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.
