The purpose of this talk is to describe the evolution of the standard RPC concept as it was formulated at the very beginning. In spite of its conceptual simplicity, the RPC can be adapted to fulfill very different tasks ranging from muon triggering-tracking at collider experiments, to the detection of Extensive Air Showers for ground based cosmic ray experiments. This talk tries to focus on...
Resistive Plate Chambers are used in the ATLAS experiment for triggering muons in the barrel region. These detectors use a Freon-based gas mixture containing C2H2F4 and SF6, high global warming potential greenhouse gases. To reduce the greenhouse gas emissions and cost, it is crucial to search for new environmentally friendly gas mixtures. In August 2023, at the end of the proton-proton...
The CMS experiment has collected more than 74 fb^-1 of proton-proton collision data at a 13.6 TeV center-of-mass energy in Run 3 data taking (2022, 2023 and early 2024). The CMS RPC system faces the challenge of the LHC expected delivered instantaneous luminosity of up to 7.5 x 10^34 cm^-2s^-1, providing redundant information for robust muon triggering, reconstruction and identification. To...
ALICE stands for "A Large Ion Collider Experiment", and it is designed to study proton–proton and heavy-ion collisions at ultra-relativistic energies at the LHC. The main goal of ALICE is to assess the properties of quark gluon plasma (QGP), a state of matter reached in extreme conditions of temperature and energy density where quarks and gluons are deconfined.
One of the main observables...
The ALICE Time Of Flight (TOF) detector, composed of 1593 Multigap Resistive Plate Chambers (RPCs) with a gas mixture of Freon (93%) and SF6 (7%), covers an active area of approximately 140 m² and includes over 150000 readout channels. During the LHC long shutdown in 2018-2022, the detector underwent a major upgrade of its readout, allowing for continuous data taking and, therefore, to handle...
