R&D of GEM-based Muon Chamber Detector for the Compressed Baryonic Matter experiment at FAIR

The Compressed Baryonic (CBM) experiment at Facility of Anti-proton and Ion Research (FAIR) is a future experiment to be held at GSI, Darmstadt, Germany.  The particle flux at the Muon Chamber (MUCH) detector of CBM experiment will reach up to 1 MHz/cm2 at the first detector station.  Out of the presently available detector technologies, Gas Electron Multiplier (GEM) technology based detectors will be used to build the first two detector stations for its high rate capability.  I have contributed to the R&D of GEM detector for its successful operation with high efficiency at a high flux of particles without any ageing due to their operation in a long-term basis. I shall briefly explain the R&D of GEM detectors. I shall also talk about the R&D of a straw tube detector for its possible use to build rest detector stations of MUCH in CBM experiment. I have built several scintillator detectors to measure the variation of the flux of cosmic ray muon at Kolkata. I shall present the results. I shall discuss my future plans in the coming year for further R&D of detectors.
