A low-resistivity RPC for the ALICE dimuon arm

In view of ALICE, the dedicated heavy-ion experiment at LHC, a resistive plate chamber (RPC) with electrodes made of low-resistivity bakelite ( rho approximately=3.5*10/sup 9/ Omega cm) has been tested at the CERN SPS both in streamer and in avalanche mode. The chamber has shown a stable behaviour a...

Descripción
Sumario:In view of ALICE, the dedicated heavy-ion experiment at LHC, a resistive plate chamber (RPC) with electrodes made of low-resistivity bakelite ( rho approximately=3.5*10/sup 9/ Omega cm) has been tested at the CERN SPS both in streamer and in avalanche mode. The chamber has shown a stable behaviour and excellent rate capability: its efficiency is better than 95% for local particle fluxes of about 1 and 10 kHz/cm/sup 2/ for operation in streamer and in avalanche mode, respectively. The cluster size and the time resolution have also been measured for both modes of operation. (22 refs).
