The CMS experiment, located at the Large Hadron Collider (LHC) in CERN, has a redundant muon system composed by three different gaseous detector technologies: Cathode Strip Chambers (in forward regions), Drift Tubes central region), and Resistive Plate (both its regions). All are used for reconstruction triggering. RPC confers robustness redundancy to trigger. operation challenging background pileup conditions of LHC environment is presented. provides information all track finders thus...
Four double-gap CMS resistive plate chambers are being tested at the CERN Gamma Irradiation Facility to determine performance and aging effects expected conditions of High Luminosity-Large Hadron Collider. Results up an integrated charge 290 millicoulomb/cm2 reported.
The high luminosity expected from the HL-LHC will be a challenge for CMS detector. increased rate of particles coming collisions and radioactivity induced in detector material could cause significant damage result progressive degradation its performance. Simulation studies are very useful these scenarios as they allow one to study radiation environment impact on Results presented RPC stations considering operating conditions at HL-LHC.
With the increase of LHC luminosity foreseen in coming years, many detectors currently used different experiments will be dramatically impacted and some need to replaced or upgraded. The new ones should capable provide time information reduce data ambiguity due expected high pileup. We propose equip CMS |η| muon chambers with pairs single gap RPC read out by long pickup strips PCB. precise measurement (0<15 ps) signal induced particles crossing detector on both ends each strip give an...
In the next decades, Large Hadron Collider (LHC) will run at very high luminosity (HL-LHC) 5×1034 cm−2s−1, factor five more than nominal LHC luminosity. During this period CMS RPC system be subjected to background rates which could affect performance by inducing aging effects. A dedicated longevity program qualify present for HL-LHC running is ongoing. At CERN Gamma Irradiation Facility (GIF++) four detectors, from spare production, are exposed an intense gamma radiation a dose equivalent...
The Muon Upgrade Phase II of the Compact Solenoid (CMS) aims to guarantee optimal conditions present system and extend $\eta$ coverage ensure a reliable for High Luminosity Large Hadron Collider (HL-LHC) period. Resistive Plate Chambers (RPCs) will upgrade off-detector electronics (called link system) chambers currently installed place improved RPCs (iRPCs) cover high pseudo$-$rapidity region, challenging region muon reconstruction in terms background momentum resolution. In order find best...
The Resistive Plate Chambers (RPC) are used for muon triggers in the CMS experiment. To calibrate high voltage working-points (WP) and identify degraded detectors due to radiation or chemical damage, a scan has been performed using 2017 data from pp collisions at center-of-mass energy of 13 TeV. In this paper, we present calibration method latest results obtained data. A comparison with all scans taken since 2011 is considered investigate stability detector performance time.
The high pseudorapidity ($\eta$) region of the Compact Muon Solenoid (CMS) muon system is covered by Cathode Strip Chambers only and lacks redundant coverage despite fact that it a challenging for muons in terms backgrounds momentum resolution. During annual Year-End Technical Stops 2022 & 2023, two new layers improved Resistive Plate (iRPC) will be added, RE3/1 RE4/1, which completely cover $1.8 < |\eta| 2.4$ endcap. Thus, additional chambers lead to increase efficiency both trigger offline...
We measure the efficiency of CMS Resistive Plate Chamber (RPC) detectors in proton-proton collisions at centre-of-mass energy 13 TeV using tag-and-probe method. A muon from a Z0 boson decay is selected as probe measurement, reconstructed inner tracker and rest systems. The overall RPC chambers during 2016–2017 collision runs measured to be more than 96% for nominal chambers.
Several theoretical models inspired by the idea of supersymmetry (SUSY) accommodate possibility Heavy Stable Charged Particles (HSCPs). The Phase II upgrade CMS-RPC system will allow trigger and identification this kind particles exploiting Time-of-Flight Technique with improved time resolution that a new Data Acquisition System (DAQ) provide (∼2 ns). Moreover, Resistive Plate Chambers (RPC) detector chambers be installed to extend acceptance coverage up |η|<2.4 similar better spatial...
The High Luminosity LHC (HL-LHC) phase is designed to increase by an order of magnitude the amount data be collected experiments. foreseen gradual instantaneous luminosity up more than twice its nominal value $10\times10^{34}\ {\rm cm}^{-1}{\rm s}^{-2}$ during Phase I and II running, presents special challenges for region with high pseudo rapidity ($\eta$) forward muon spectrometer ($2.4 > |\eta| 1.9$) not equipped RPC stations. expected particles rate 2 kHz cm$^{-1}$ ( including a safety...
