RPC performance versus front-end electronics and detector parameters

Abstract

In this paper we review the performances of the RPC detector versus the parameters characterizing the front-end electronics. The use of RPCs in collider experiments required a substantial increase of the rate capability compared to what could be reached in streamer working mode. That was achieved working in saturated avalanche mode, where the charge delivered in the gas was much lower than in streamer mode. The High luminosity LHC and the future colliders will require even larger rate capability in the muon spectrometers compared to the current one, which can be obtained with a further improvement of the front-end electronics. This improvement consist in lowering the front-end threshold in order to detect lower charge avalanches and at the same time to improve the signal to noise ratio.
