Multistrip multigap symmetric RPC

Abstract The characteristics of a symmetric multigap resistive plate chamber with multistrip readout electrode, recently developed by us, continued to be investigated. Studies of the time resolution, efficiency, average charge and dark rate as a function of applied voltage and the influence of the angle of incidence of the detected particle on these observables have been performed. Different type of discriminators have been tested

A large-area glass-resistive plate chamber with multistrip readout

Abstract A completely new configuration of a glass resistive-plate chamber (GRPC) was built and tested. It consists of a double two-gap structure of electrodes with an active area of about 400 cm 2 and is read out via a central multistrip printed circuit board. In measurements with a 60 Co source and p, d particles of 1.5 A GeV time resolutions better than 80 ps , position resolution along the strips of 5– 6 mm and efficiencies larger than 95% were obtained using available fast standard electronics. These results open the possibility of constructing compact TOF detectors of high resolution and high granularity
