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 spectrometer (instrumented with bakelite RPCs and drift tubes).
The RPCs are operated in streamer...

During the months of july-september 2009 CMS has taken data from cosmic particles keeping the magnetic field on. This data taking was called Cosmics Runs At Four Tesla (CRAFT). CRAFT 2009 was a chance to measure the flexibility and the stability of the Level 1(L1) Trigger of RPCs . The Pattern Comparator (PAC) is the RPC L1 Trigger algorithm : during CRAFT it was modified in order to be better...

Muon detection plays a key role at the Large Hadron Collider. Resistive Plate Chambers (RPC) provide the barrel region of the ATLAS detector with an independent muon trigger as well as a twocoordinate measurement. The chambers, arranged in three concentric layers, are operated in a strong magnetic toroidal field and cover a surface area of about 4000 m2.
The RPC Detector Control System is...

Detailed studies on the behavior of ATLAS RPCs have been performed during last year of commissioning by using cosmic rays data and the first proton-proton collisions at 450 GeV.
Detector parameters like the environment variables (temperatures, pressures, gas mixture) or other working parameters (high voltage levels, front-end discriminating thresholds, pull-down currents) have been used to...

Resistive Plate Chambers (RPC) were installed in the barrel region of ATLAS detector to provide the muon trigger (and a coarse measure of the “non-bending” phi coordinate) in the region |eta| < 1.05. The RPC are gaseous detector which measure the muon trajectory with 3 cm strips in the bending plane (r-z) and in the orthogonal direction (r-phi) with few nanoseconds time resolution. The trigger...
