Ageing test of RPC for the Muon Trigger System for the ALICE experiment
/ Arnaldi, Roberta ; Baldit, A ; Barret, V ; Bastid, N ; Blanchard, G ; Chiavassa, E ; Cortese, P ; Crochet, P ; De Marco, N ; Dellacasa, G et al.
The trigger detectors for the Muon Forward Spectrometer of the ALICE experiment will be single gap RPCs with low-resistivity bakelite electrodes. The detector will take data for different colliding systems resulting in a wide range of working conditions and requirements, especially concerning position resolution and lifetime. [...]

The performance of RPCs with bakelite electrodes of resistivity under high radiation fluxes
/ Cwiok, M ; Dominik, Wojciech ; Górski, M ; Królikowski, J
Three medium-size Resistive Plate Chambers (RPCs) with bakelite electrodes having resistivity of 5*10/sup 8/, 5*10/sup 9/ and 3*10 /sup 10/ Omega cm were tested in the Gamma Irradiation Facility at CERN in 1997, 1998 and 1999. The 2 mm gap modules working in an Inverted Double Gap configuration filled with gas mixtures containing freon C/sub 2/H/sub 2/F/sub 4/ and operated in avalanche mode exhibit wide efficiency plateau, good time resolution and small time walk due to rate variation even at intensities as high as 1 kHz/cm/sup 2//gap of a continuous radiation flux. [...]

Streamer free operation of a 2 mm gap resistive plate chamber with $C_{2}F_{5}H$
/ Cerron-Zeballos, E ; Crotty, Ian ; Hatzifotiadou, D ; Lamas-Valverde, J ; Williams, M C S ; Zichichi, A
It is necessary to operate the resistive plate chamber (RPC) in avalanche mode to obtain high efficiency at elevated particle fluxes. We examine this mode of operation with a 2 mm gap RPC using gas mixtures containing C/sub 2/F/sub 4/H/sub 2/ and C/sub 2/F/sub 5/H. [...]

Ageing tests on the low-resistivity RPC for the ALICE dimuon arm
/ Arnaldi, R ; Baldit, A ; Barret, V ; Bastid, N ; Blanchard, G ; Chiavassa, E ; Cortese, P ; Crochet, Philippe ; De Marco, N ; Dellacasa, G et al.
The trigger for the Dimuon Forward Spectrometer of the forthcoming ALICE experiment at CERN LHC will be provided by low-resistivity, single gap Resistive Plate Chambers working in streamer mode. Different ageing test were performed to measure and improve the life- time of the detector. [...]

The micro-gap resistive plate chamber
/ Cerron-Zeballos, E ; Hatzifotiadou, D ; Lamas-Valverde, J ; Platner, E D ; Roberts, J ; Williams, M C S ; Zichichi, A
Previously we have found that the freon C/sub 2/F/sub 5/H has very good properties when used in a resistive plate chamber (RPC) with a single gap of 2 mm. In this paper we report on the performance of a multigap RPC consisting of 4 gaps of 0.8 mm filled with a gas mixture containing this freon. [...]
