Resistive Plate Chambers (RPC) provide the barrel region of the ATLAS detector with an independent muon trigger and a two-coordinate measurement.
The chambers, arranged in three concentric double layers are operated in a strong magnetic toroidal field and cover a surface area of about 4000 m2.
During 2011 the LHC has provided proton-proton collisions at 7 TeV in the center-of-mass frame with...

We show ATLAS RPC timing performance measured with proton-proton collisions
and cosmic rays in data recorded by the ATLAS detector in 2011 at LHC.
In addition, we illustrate how RPC time-of-flight and spatial
measurements can be used to determine particle velocity and direction at LHC.

ALICE (A Large Ion Collider Experiment) is the LHC experiment dedicated to the study of heavy-ion collisions at very high energy, where the formation of the Quark Gluon Plasma (QGP) is expected.
Heavy flavor production is one of the key observables for the study of QGP.
In ALICE, charmonium and bottomonium states are identified in the forward rapidity region via their muonic decays, by...

The large Time-Of-Flight (TOF) array is one of the main detectors devoted to charged hadron identification in the mid-rapidity region of the ALICE experiment at the LHC; it allows separation among pions, kaons and protons up to few GeV/c, covering the full azimuthal angle and -0.9 < η < 0.9. The TOF exploits the innovative MRPC technology capable of an intrinsic time resolution better than 50...

OPERA is an experiment dedicated to the observation of numu into
nutau oscillations through tau appearance on the CNGS beam.
The experiment is composed by two identical super-modules, each
with a target section (made of emulsion/lead bricks alternated to
a scintillator Target Tracker) and a muon spectromter (instrumented
with bakelite electrodes RPCs and drift tubes).

The ARGO-YBJ experiment consists of a 5000 m2 single layer of Resistive Plate Chambers situated at Yangbajing, Tibet (P.R. of China), 4300 meters a.s.l. (atmospheric depth 600 g/cm2). The percentage of active area all over the carpet is 92% and a partially instrumented guard ring (1700 m2) around the central zone extends the instrumented area up to 11000 m2.
The experiment is operated in...

The Extreme Energy Events experiment has been concieved by its leader, prof. A. Zichich, and joins the scientific interest of a real cosmic rays physics experiment with the enormous didactic potentiality deriving from letting it be carried on by high school students. It consists of an extended network of telescopes made by three Multigap Resistive Plate Chambers each, designed to monitor the...

Data taken over the last several years have demonstrated that RHIC has created dense and rapidly thermalizing matter. One of the physics goals for the next decade of RHIC is to study the fundamental properties of hot, dense medium such as temperature, density profile, and color screening length via electro-magnetic probes such as di-leptons. Muons have a clear advantage over electrons due to...

The Compressed Baryonic Matter (CBM) experiment, proposed at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, has decided to use MRPC technology to build the TOF wall. Compared with other experiments (for instance Alice, STAR, et al), CBM-TOF requires a rate capability for MRPC as high as 20 kHz/cm2. Tsinghua University is a group member of CBM-TOF and is doing research...

The proposed Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, will use a TOF system based on MRPC technology for hadron identification. The challange is to keep efficiencies above 90 % and time resolutions well below 80 ps at particle fluxes up to 20 kHz/cm2, which is not accessible to conventional float-glass...

The Compressed Baryonic Matter spectrometer (CBM) is expected to be operational in the year 2018 at the Facility for Anti-proton and Ion Research (FAIR) in Darmstadt, Germany. The key element providing hadron identification at incident energies between 2 and 45 AGeV is a time-of-flight wall placed at 10 m distance from the target covering the polar angular range from 2.5º - 25º and full...

The hadron photo-production experiment at LEPS2/SPring-8 will start in 2013. The photon beam with energy up to 3 GeV is produced by backward Compton scattering of laser photons with 8-GeV electrons circulating in SPring-8 storage ring. The development of a 4pi detector is now underway. The momentum of a charged particle is analyzed with the solenoid magnet and drift chambers. The particle...

We report a systematic study of oiled phenolic multigap RPCs for high-rate particle triggers in high-energy physics experiments. In the current R&D, four- and six-gap detector structures were applied to the typical panel-type RPCs. Reduction of avalanche charges drawn in the trigger RPCs will be fairly conductive to lessen the possibility of radiation damage as well as to enhance the detector...

The CMS muon endcap system presently comprises three disks of RPCs, with a fourth disk under preparation with detectors and associated services. This new station, RE4, will be installed in the LHC first Long Shutdown during 2013-2014. In this talk we describe the new RPCs developed for this upgrade, based on lessons learnt from the earlier work. We report on tests performed after the assembly...

Since RPCs were proposed to build a time-of-flight wall for relativistic ions in the framework of the R3B experiment at FAIR-GSI [1], we have carried out an extensive programme to study the timing RPC performances under heavy ion irradiation [2, 3]. In the last two years, several detector tests at the heavy ion GSI facility (Darmstadt, Germany) and the electron beam ELSA facility at CEA/DAM...

The FOPI experiment has upgraded its Time-of-Flight detection system with a glass based RPC detector. This implementation is unique since readout electrodes are 1.64 mm narrow strips 90 cm long. Each counter is composed of 16 strips and referred to as the Multi-strip Multi-Gap Resistive Plate Counter (MMRPC). Counters are placed around the Central Drift Chamber of FOPI forming a cylindrical...

poster presentation
ATLAS RPC Detector Control System has been mainly used to monitor and safely operate the RPC detector during 2010 and 2011 LHC run.
The large number (~3500) of gap currents, individually monitored with nA accuracy, allowed us to study the detector behavior with a growing Luminosity and beam currents.
A clear linear correlation between the average gap current and the luminosity has been...
