Description
The CMS experiment, located at the CERN Large Hadron Collider, has a redundant muon system composed by three different detector technologies: Cathode Strip Chambers (in the forward regions), Drift Tubes (in the central region), and Resistive Plate Chambers (both its central and forward regions). All three are used for muon reconstruction and triggering.
However the high pseudo-rapidity region of CMS muon system is covered only by Cathode Strip Chambers (CSC) and lacks redundant coverage despite the fact that it is a challenging region for muons in terms of backgrounds and momentum resolution. In order to maintain good efficiency for the muon trigger in this region additional Resistive Plate Chambers (RPCs) are planned to be installed. RPCs with fine granularity and high timing resolution will be used to mitigate the background effects and complete the redundancy of the system. The ongoing R&D activities will be presented in the talk.
