We report a development of oiled multi-gap RPCs for high-rate particle triggers in high-energy physics experiments. RPCs with higher rate capability is promising, especially, for effective muon triggers at the RE1/1 region of the CMS in the LHC experiment. In this study, we designed and built two six-gap prototype RPCs made of 1-mm thick melamine-based high pressure laminated (HPL) resistive...

The work presented here describes the characterization of double gap, bakelite RPCs
for the end-cap region of the “Compact Muon Solenoid” experiment at LHC, which
were built, assembled and tested in India, before their dispatch to CERN in 2008.
These detectors consisted of eight of RE*/2 and two of RE*/3 type geometry for the
CMS. The RE*/2 detectors had gas-gaps made at KODEL, Korea and...

The muon trigger upgrade of PHENIX includes the construction and installation of resistive plate chambers (RPCs) in the forward muon spectrometers and to upgrade the frontend electronics of the existing muon tracking chambers.
About 300 gas gaps were produced, passed strict quality assurance procedures and are presently being assembled into RPC-1 and RPC-3 stations.Recently, the installation...

The India-based Neutrino Observatory (INO) colllaboration is planning to build a massive 50kton magnetised iron calorimeter (ICAL) detector to study atmospheric neutrinos. About 30,000 2m x 2m size glass RPCs will be used as active detector elements. Starting with a small 30cm x 30cm size RPCs, we have now started developing full size 2m x 2m RPCs. The production method for this large size...

The India-based Neutrino Observatory (INO) colllaboration is planning to build a massive 50kton magnetised iron calorimeter (ICAL) detector using glass RPCs as active detector elements. A stack of 12 such glass RPCs of 1m x 1m in area are tracking cosmic ray muons over the last two years. In this paper, we will review the performance of the RPCs using this cosmic ray data collected so far.

High resistive bakelite RPCs, made with silicone compound coating, applied to the inner electrode surfaces, are studied in a cosmic ray test bench. The long term tests of the RPCs operated in streamer mode with gas mixture of Ar/isoC4H10/R-134a= 34/7/59 (mass ratio), show stable efficiency > 90% and time resolution ~ 2 ns (FWHM). Comparative studies of performance of the RPCs, made with...
