Study of resistive plate chambers for the ALICE dimuon spectrometer

The trigger system of the ALICE dimuon spectrometer is based on RPC detectors. We present experimental results of a beam test about rate capability, time resolution and cluster size of single gap RPC detectors operating both in `streamer mode' and in `avalanche mode'. We have compared the...

Descripción
Sumario:The trigger system of the ALICE dimuon spectrometer is based on RPC detectors. We present experimental results of a beam test about rate capability, time resolution and cluster size of single gap RPC detectors operating both in `streamer mode' and in `avalanche mode'. We have compared the performances of small chambers (50*50 cm/sup 2/) built with bakelite of different resistivity, from ~3.10/sup 9/ Omega cm to ~3.10/sup 11/ Omega cm. For the low resistivity RPC we obtained a rate capability of several hundreds of Hz/cm/sup 2/ when it is operating in `streamer mode', and of several thousands of Hz/cm/sup 2 / when it is operating in `avalanche mode'.
