Experiences from the RPC data taking during the CMS RUN-2 / CMS Collaboration
The CMS experiment recorded 177.75 fb$^{-1}$ of proton-proton collision data during the RUN-$1$ and RUN-$2$ data taking period. Successful data taking at increasing instantaneous luminosities with the evolving detector configuration was a big achievement of the collaboration. [...]

CMS RPC Activities During LHC LS-2 / CMS Collaboration
The second LHC long shutdown period (LS2) is an important opportunity for the CMS Resistive Plate Chambers (RPC) to complete their consolidation and upgrade projects. The consolidation includes detector maintenance for gas tightness, HV (high voltage), LV (low voltage) and slow control operation. [...]

Improved RPC for CMS muon system upgrade for HL-LHC / CMS Collaboration
During the Phase-2 of the LHC, known as the High Luminosity LHC (HL-LHC), the accelerator will increase its instantaneous luminosity to 5 $\times$ 10$^{34}$ cm$^{-2}$ s$^{-1}$, delivering an integrated luminosity of 3000~fb$^{-1}$ over 10 years of operation starting from 2027. In view of the HL-LHC, the CMS muon system will be upgraded to sustain efficient muon triggering and reconstruction performance. [...]

CMS RPC Background -- Studies and Measurements / CMS Collaboration
The expected radiation background in the CMS RPC system has been studied using the MC prediction with the CMS FLUKA simulation of the detector and the cavern. The MC geometry used in the analysis describes very accurately the present RPC system but still does not include the complete description of the RPC upgrade region with pseudorapidity $1.9 < \lvert \eta \rvert < 2.4$.

Upgrade of the CMS Resistive Plate Chambers for the High Luminosity LHC / CMS Collaboration
During the upcoming High Luminosity phase of the Large Hadron Collider (HL-LHC), the integrated luminosity of the accelerator will increase to 3000 fb$^{-1}$. The expected experimental conditions in that period in terms of background rates, event pileup, and the probable aging of the current detectors present a challenge for all the existing experiments at the LHC, including the Compact Muon Solenoid (CMS) experiment.

Effects of the electronic threshold on the performance of the RPC system of the CMS experiment / CMS Collaboration
Resistive Plate Chambers have a very important role as the dedicated system for muon triggering both in the barrel and in the endcap regions of the CMS experiment at the Large Hadron Collider. In order to optimize its performance, it is of primary importance to tune the electronic threshold of the front-end boards reading the signals from these detectors. [...]

CMS phase-II upgrade of the RPC Link System / CMS Collaboration
The present RPC Link System has been servicing as one of the CMS subsystems since installation in 2008. Although the current Link System has been functioning well for the past 13 years, the aging of its electronic components and lack of radiation hard ASICs could present problems for future operations.

Research and development of the back-end electronics for the two-dimensional improved resistive plate chambers in CMS upgrade / CMS Collaboration
To complement and ensure redundancy in the endcap muon system of the Compact Muon Solenoid (CMS) detector and to extend the Resistive Plate Chamber (RPC) system coverage, improved RPCs (iRPCs) with either orthogonal layer strips with one-end electronics or single layer strips with two-end electronics providing more precise time measurement will be installed in the very forward pseudorapidity region of $|\eta |<2.4$. The iRPC readout system needs to support two-dimensional (2D) or two-end readout. [...]

Towards a two-dimensional readout of the improved CMS Resistive Plate Chamber with a new front-end electronics / CMS Collaboration
As part of the Compact Muon Solenoid experiment Phase-II upgrade program, new Resistive Plate Chambers will be installed in the forward region. High background conditions are expected in this region during the high-luminosity phase of the Large Hadron Collider, therefore an improved RPC design has been proposed with a new front-end electronics to sustain a higher rate capability and better time resolution.

Aging Study on Resistive Plate Chambers of the CMS Muon Detector for HL-LHC / CMS Muon Group Collaboration
In the High Luminosity Large Hadron Collider (HL-LHC) program, during the next years, the instantaneous luminosity will increase up to 5 $\times$ 10$^{34}$ cm$^{-2}$ s$^{-1}$ which means a factor five higher than the nominal LHC. In that period, the present CMS Resistive Plate Chambers (RPC) system will be subjected to background rates higher than those for which the detectors have been designed, which could affect the detector properties and induce aging effects.
