In view of the Phase-2 of the LHC physics program, called High Luminosity LHC (HL-LHC), the CMS muon system will be upgraded to maintain a robust muon triggering and reconstruction performance. Therefore RE3/1 and RE4/1 stations of the forward muon system will be equipped with new improved Resistive Plate Chambers (iRPC) as dedicated detectors for muon triggering in CMS. The new iRPC detectors...
The ATLAS Muon Spectrometer is set for a significant upgrade as part of the High-Luminosity LHC (HL- LHC) program, which includes the installation of three additional full coverage layers of new generation thin-gap Resistive Plate Chambers (RPCs) in the inner barrel region. These RPCs feature a reduced gas gap thickness of 1 mm between high-pressure phenolic laminate (HPL) electrodes,...
A Large Ion Collider Experiment (ALICE) is one of the four large experiments at the CERN Large Hadron Collider (LHC) and it is designed to study the physics of Quark Gluon Plasma (QGP) using ultra-relativistic Pb-Pb collisions. To study the muonic decays of heavy quarks, ALICE is equipped with a Muon Spectrometer located at forward rapidity, which includes the Muon IDentifier (MID), a system...
Multi-gap resistive plate chamber (MRPC) has been adopted to construct the inner Time-of-Flight (TOF) detector for the CEE experiment at HLEF. Its mass production started in May 2024. The production procedure and related quality control (QC) are described. A preliminary status of the MRPC production and the test results with cosmic rays is given. The inner TOF covers a total area of...
The current RPC system is undergoing a major upgrade, consisting in the installation of approximately 1000 RPC detector units of new generation in the innermost barrel layer of the ATLAS Muon Spectrometer. The goal of the project is to increase the detector coverage, currently limited to approximately 80%, and improve the trigger robustness and efficiency. The production of the gas volumes...
In order to cope with the High-Luminosity Large Hadron Collider, the current ATLAS Muon system foresees a significant upgrade during the Long Shutdown-3.
For the muon trigger, three layers of thin-gap Resistive Plate Chambers (RPC) will be added to the BI (Barrel Inner) region.
This new generation of RPC benefits from the thin-gap structure to achieve the required higher rate capability....
A new generation of Resistive Plate Chambers have been developed for the ATLAS phase-2 upgrade in sight of the High-Luminosity phase of the Large Hadron Collider. These RPCs consist in three independent 1 mm gas gaps(singlets) equipped with a newly low-threshold Front-End electronics, assembled in the same mechanical structure(triplet). During 2024 the production of the phase-2 RPCs started...
