Effects of the electronic threshold on the performance of the RPC system of the CMS experiment

Resistive Plate Chambers (RPCs in the following) play a very important role as the dedicated system for muon triggering both in the barrel and in the endcap of the CMS experiment at the Large Hadron Collider. It is therefore of primary importance to tune the operating voltage and the electronic threshold of the front-end boards reading the signals from these detectors in order to optimize the RPC system performance. In this study we present the results of a threshold voltage scan, and in particular the effects of changing the electronics threshold voltage on the RC efficiency, cluster size and detector intrinsic noise rate.
