This talk delves into the crucial enhancements of the RPC system as part of the comprehensive upgrades to the CMS Level-1 Тrigger, tailored to address the increased luminosity challenges at the HL-LHC. The revised Level-1 architecture maximizes the integration and utility of the muon subsystems—CSC, DT, and particularly the RPC—to ensure superior performance and reliability under extreme...
One of the upgrades of CMS RPC system is the installation of new chambers - the improved RPC - with a new readout technology, achieving a space resolution along the strip of about ~2cm, enabling the inclusion of the RPC hit in the CMS muon reconstruction. The main characteristic of the iRPC is the two side strip readout which makes a new clusterization algorithm necessary. The algorithm was...
This poster introduces an extension to the Analytical Method clustering algorithm designed for the Barrel Muon Track Finder Layer 1 (BMTL1) for HL-LHC. The new extension leverages the enhanced timing capabilities of the CMS RPC system. The new algorithm significantly reduces the prefiring of muons. This method addresses challenges associated with high particle flux environments, ensuring...
This poster presents the development of RPC L1 Trigger clustering within the CMS software framework, CMSSW, incorporating the improved timing capabilities of RPC chambers. The integration of these upgrades significantly enhances the resolution and reliability of the L1 Trigger emulator, enabling more precise trigger responses. The presentation will detail the technical advancements in...
The CMS experiment is collecting proton-proton collisions at the center-of-mass energy of 13.6TeV in LHC Run 3. RPC detector is one of the sub-detectors of the CMS muon system which is capable of triggering and reconstruction of muons. In this poster, efficiency of the CMS RPC detector during the Run 3 data taking period is presented. The Tag-and-Probe method with the decay of the Z boson to...
The HV scan is a crucial sequence of calibration runs typically conducted at the onset of each data-taking year with the initial collisions of the CERN Large Hadron Collider (LHC) at nominal luminosity. This procedure ensures the proper functioning of the Resistive Plate Chamber (RPC) detectors at the Compact Muon Solenoid (CMS) experiment at CERN by establishing correct working points. In the...
The Compact Muon Solenoid (CMS) is a general purpose experiment to explore the physics of the TeV scale in pp-collisions provided by the CERN LHC. Muons constitute an important signature of new physics and their detection, triggering, reconstruction and identification is guaranteed by various sub-detectors using different detection systems: Drift Tubes (DT) and Resistive Plate Chambers (RPC)...
