CMS iRPC FEB development and validation / CMS Muon Collaboration
In view of the High Luminosity upgrade of the CERN LHC, the forward CMS Muon spectrometer will be extended with two new stations of improved Resistive Plate Chambers (iRPC) covering the pseudorapidity range from 1.8 to 2.4. Compared to the present RPC system, the gap thickness is reduced to lower the avalanche charge, and an innovative 2D strip readout geometry is proposed. [...]

Latest results of Longevity studies on the present CMS RPC system for HL-LHC phase / CMS Muon Collaboration
The present Compact Muon Solenoid Resistive Plate Chambers system has been worked efficiently during Run I and Run II of data taking period (Shah et al., 2020) [1]. In the coming years of operation with the High Luminosity LHC (HL-LHC), the expected rate and integrated charge are expected to be about 600 Hz/cm2 and 840 mC/cm2, respectively (including a safety factor of three).

New slow control emulator for the CMS phase-2 upgrade RPC link system / CMS Muon Collaboration
The CERN Compact Muon Solenoid (CMS) RPC system phase-2 upgrade project is in good progress. It covers the replacement of the off-detector electronics for the present Resistive Plate Chambers (RPC), known as “link system”, and includes the renovation of the legacy slow controller with brand new electronics, called RPC backend electronics.

RPC background studies at CMS experiment / CMS Muon Collaboration
During Run2 the high instantaneous luminosity, up to 2.21034cm−2s−1, lead to a substantial hit rate in the Compact Muon Solenoid experiment’s muon chambers due to multiple background sources to physics processes sought for at LHC. In this article we will describe the analysis method devised to measure and identify the contributions to such background in the Resistive Plate Chambers. [...]

The CMS RPC system readiness for LHC Run-3 data taking / CMS Muon Collaboration
During Run-3, the LHC is preparing to deliver instantaneous luminosity in the range from 5 × 1034 cm−2 s−1 to 7.5 × 1034 cm−2 s−1. To ensure stable data taking, providing redundant information for robust muon triggering, reconstruction and identification, the CMS RPC collaboration has used the opportunity given by the LHC long shutdown 2 (LS2), to perform a series of maintenance and preparation activities for the new data taking period.

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. [...]

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. [...]
