The CMS Resistive Plate Chambers (RPC) system consists of 912 double-gap chambers. The challenging constrains on the design and operation of this system imposed the development of a complex Detector Control System to assure the operational stability and reliability of a so large and complex detector and trigger system . The final layout and functionality of the CMS RPC DCS as well as the...

The ARGO-YBJ air-shower array is composed of 1836 Resistive Plate Chambers operated instreamer mode, with a total sensitive area of about 6400 m2. The experiment, with its complete layout, has been running almost uninterruptedly since October 2007. The main working features of the detector, namely the operating current of each gas volume, atmospheric pressure, temperature and relative...

The CMS muon system consists of three gaseous detectors with complementary features: the Drift Tubes chambers (DT) in the barrel and the Cathode Strips Chambers in the endcaps provide good spatial resolution and the Resistive Plate Chambers (RPC) have an excellent time resolution. These three detectors provide muon trigger for the hardware Level-1 trigger. The informations transmitted from the...

The forward Muon Spectrometer of the ALICE experiment aims at investigating the properties of strongly interacting matter at the extreme energy density reached in heavy ion collisions at LHC. The trigger system of the Muon Spectrometer, called Muon Trigger, consists of four planes of RPC (Resistive Plate Chamber) detectors with a total area of 140 m2, 21k frontend channels and fast-decision...

Many significant questions remain to be answered about the origin of the proton spin. A new fast Resistive Plate Chamber (RPC) based trigger system is being developed for the PHENIX muon spectrometer arms that will allow for the first time the measurement of the flavor structure of the quark polarization in the proton through the observations of W-bosons in polarized proton-proton collisions...

In the ARGO-YBJ experiment, the charge readout is performed on two Big Pads equipped in each RPC to measure the charged particle density of the shower front up to 104/m2, enabling the study of primaries with energies in the "Knee" region. It's the first time for RPCs being used this way. To calibrate the number of charged particles injected on one RPC versus its charge readout, a telescope is...
