In view of ALICE, the dedicated Heavy-Ion Experiment at LHC, a Resistive Plate Chamber (RPC) with electrodes made of low-resistivity bakelite (rho similar or equal to 35 x 10(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(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. (C) 2000 Elsevier Science B.V. All rights reserved.

Abstract
In view of ALICE, the dedicated Heavy-Ion Experiment at LHC, a Resistive Plate Chamber (RPC) with electrodes made of low-resistivity bakelite (rho similar or equal to 35 x 10(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(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. (C) 2000 Elsevier Science B.V. All rights reserved.File in questo prodotto:
