CMS RPC muon detector performance with 2010-2012 LHC data

TL;DR

This paper reports on the performance, stability, and background radiation levels of the CMS RPC muon detector system during the initial three years of LHC operation, including future extrapolations for higher luminosities.

Contribution

It provides a comprehensive analysis of RPC system performance metrics and background radiation levels, with projections for future collider conditions.

Findings

RPC efficiency remained stable over three years

Measured background radiation levels increase with LHC luminosity

Extrapolated performance for High Luminosity LHC conditions

Abstract

The muon spectrometer of the CMS (Compact Muon Solenoid) experiment at the Large Hadron Collider (LHC) is equipped with a redundant system made of Resistive Plate Chambers and Drift Tube in barrel and RPC and Cathode Strip Chamber in endcap region. In this paper, the operations and performance of the RPC system during the first three years of LHC activity will be reported. The stability of RPC performance, such as efficiency, cluster size and noise, will be reported. Finally, the radiation background levels on the RPC system have been measured as a function of the LHC luminosity. Extrapolations to the LHC and High Luminosity LHC conditions are also discussed.
