Gaseous detectors have come a long way from the invention of the multiwire proportional chamber, and have been exploited for charged particle tracking over the last few decades. This progress, from previous generation experiments to the present Large Hadron Collider experiments has had a dramatic impact on the conception and design of large area gaseous detectors for muon trigger and...

The ALICE muon spectrometer is equipped with a trigger system made of four RPC planes, arranged in two stations. The aim of the system is to deliver single and di-muon triggers with suitable transverse momentum cut, optimised for the physics of quarkonia and open heavy flavour.
In the first two years of LHC operation, the RPCs (72 in total) were operated in highly saturated avalanche mode...

PAttern Comparator Trigger (PACT) is a component of the Level-1 Muon Trigger of the CMS experiment. PACT uses signals from RPC detectors to reconstruct muon candidates for CMS. This trigger component was contributing to CMS trigger decision during LHC operation in 2010 and 2011. In this presentation the PACT system is described. Its performance is given.

The LEPS2/SPring-8 experiment of photo-production of vector mesons and hyperons is scheduled to start in 2013. The photon beam with energy up to 3 GeV is produced by backward Compton scattering of laser photon with 8 GeV electrons inside SPring-8 storage ring. The development of a 4pi detectors and the construction of a solenoid magnet is currently underway.

The present ATLAS forward muon spectrometer (Small Wheel), which covers a range in rapidity 1.3 < η < 2.7, is not designed to withstand the super LHC luminosity up to 5 x 1034 cm-2s-1. The main issues are coming from the very high background rate, up to 14 kHz/cm2, extrapolated from the present data, and from the necessity to drastically improve the muon momentum trigger selectivity. To...

During the first two long shutdowns of the Large Hadron Collider which are presently scheduled for 2013/2014 and 2017/2018, several detector upgrades are foreseen by the CMS Collaboration to prepare for the ultimate luminosity of more than 10^34/cm^2/s at 14 TeV that should be achieved during the first 10 year period of the accelerator (LHC Phase 1). In particular, the present Resistive Plate...

A joint effort from China, Italy and US institutes and laboratories on thin-gap RPC development for high rate capability, excellent time precision and good spatial resolution will be reported with test beam results. The performance of several prototype RPCs which have 1 mm gas gaps and 1-3 mm readout strip sizes will be addressed. Tests at backgrounds as high as 7KHz/cm**2 will be...

Very large systems of RPCs with 2 mm gas gap are presently working at LHC as
muon trigger detectors. In order to conceive a new generation of RPCs, fully
adequate to the needs of the high luminosity super-colliders of the next future,
two aspects have to be reconsidered: the gap width which determines the
amount of charge delivered in the gas per detected avalanche and the front...

Multi-gap resistive plate chambers are proposed to build the Time of Flight wall of the Compressed Baryonic Matter experiment (CBM) with a time resolution better than 80 ps. The high fluxes expected at the innermost part of the detector, ~20 x 10^3 cm^{-2} s^{-1} have made necessary the development of new materials capable of withstanding such fluxes.
At Helmholtz Zentrum Dresden-Rossendorf,...

The India-based Neutrino Observatory (INO) collaboration has proposed to build a 50kton magnetized Iron Calorimeter (ICAL) detector with the primary goal to study neutrino oscillations, employing around 28,800 Resistive Plate Chambers (RPCs) as active detector elements. The ICAL detector will comprise of three modules, each of dimension 16m x 16m x 14.5m, housed inside a cavern with a rock...

Muon triggering at the super LHC luminosity imposes very strict requirements on the trigger concerning not only the rate capability but also to the tracking accuracy. This is particularly true for the very forward regions for which the LHC experiments are scheduling upgrade plans.
An accurate 3D tracking allows defining a sharp threshold in the muon transverse momentum. Moreover high...
