Abstract

The first Resistive Plate Chambers detectors were developed for cosmic ray experiments, where low rate capability, good time resolution and low cost per unit of area were needed. These same features, except for the low rate capability, were required in the muon spectrometers of the collider experiments like LHC. For this purpose newRPCdetectors with increased rate capability were developed. The rate capability improvement has been achieved thanks to the transition from streamer to saturated avalanche regime, in which the average charge produced in the gas dicharge is smaller. The price to pay for this working mode switch is the transfer of the amplification from the detector to the FE electorinics. The High luminosity LHC and the future colliders will require even greater rate capability in the muon spectrometer compared to the current one. For this reason, further improving of the rate capability is required. The transition from the saturated avalanche to a low saturated avalanche regime moves in this direction and needs a new front end electronics with better signal to noise ratio, because the average induced charge on the electrode is even smaller. The front end electronics design is crucial for the RPC performances. In this paper we discuss the performances of the RPC detector changing the front end design and the detector parameters.
