(Rio de Janeiro State U.) et al. /CMS Muon Group
The muon system of the CERN Compact Muon Solenoid (CMS) experiment includes more than a thousand Resistive Plate Chambers (RPC). They are gaseous detectors operated in the hostile environment of the CMS underground cavern on the Large Hadron Collider where pp luminosities of up to $2\times 10^{34}$$\text{cm}^{-2}\text{s}^{-1}$ are routinely achieved.

MoEDAL-MAPP, an LHC Dedicated Detector Search Facility / MoEDAL-MAPP Collaboration
During LHC's Run-2 the MoEDAL experiment, the LHC's first dedicated search experiment, took over 6 fb^-1 of data at IP8, with p-p and Pb-Pb collisions, operating with 100% efficiency. [...]

RPC based tracking system at CERN GIF++ facility / CMS Muon Collaboration
With the HL-LHC upgrade of the LHC machine, an increase of the instantaneous luminosity by a factor of five is expected and the current detection systems need to be validated for such working conditions to ensure stable data taking. At the CERN Gamma Irradiation Facility (GIF++) many muon detectors undergo such studies, but the high gamma background can pose a challenge to the muon trigger system which is exposed to many fake hits from the gamma background.

R&D; of back-end electronics for improved resistive plate chambers for the phase 2 upgrade of the CMS end-cap muon system / CMS Muon Collaboration
The Large Hadron Collider (LHC) at European Organization for Nuclear Research is planned to be upgraded to the high luminosity LHC. Increasing the luminosity makes muon triggering reliable and offline reconstruction very challenging. [...]

Search for highly-ionizing particles in $pp$ collisions at the LHC’s Run-1 using the prototype MoEDAL detector / MoEDAL Collaboration
A search for highly electrically charged objects (HECOs) and magnetic monopoles is presented using 2.2 fb-1 of p - p collision data taken at a centre of mass energy (ECM) of 8 TeV by the MoEDAL detector during LHC's Run-1. The data were collected using MoEDAL's prototype Nuclear Track Detector array and the Trapping Detector array. [...]

Search for magnetic monopoles produced via the Schwinger mechanism / MoEDAL Collaboration
Schwinger showed that electrically-charged particles can be produced in a strong electric field by quantum tunnelling through the Coulomb barrier. By electromagnetic duality, if magnetic monopoles (MMs) exist, they would be produced by the same mechanism in a sufficiently strong magnetic field. [...]

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. [...]

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. [...]
