“…For the last several decades, various types of micro-pattern gas detectors (MPGD) have been developed for their use in experiments at major accelerator facilities as well as for applications in imaging technologies. Gas Electron Multiplier (GEM) detectors, developed at CERN in 1997 [1,2], is one of the new generation MPGD, which fulfils the stringent conditions of existing and proposed large scale experiments. With increasing energy and beam luminosity in accelerator facilities, the requirements for detector technologies have been continuously changing.…”

a b s t r a c tLarge area Gas Electron Multiplier (GEM) detectors have been the preferred choice for tracking devices in major nuclear and particle physics experiments. Uniformity over surface of the detector in terms of gain, energy resolution and efficiency is crucial for the optimum performance of these detectors. In the present work, detailed performance study of a 10 Â 10 cm 2 triple GEM detector operated using Ar and CO 2 gas mixtures in proportions of 70:30 and 90:10, has been made by making a voltage scan of the efficiency with 106 Ru-Rh β-source and cosmic rays. The gain and energy resolution of the detector were studied using the X-ray spectrum of 55 Fe source. The uniformity of the detector has been investigated by dividing the detector in 7 Â 7 zones and measuring the gain and energy resolution at the centre of each zone. The variations of the gain and energy resolution have been found to be 8.8% and 6.7%, respectively. These studies are essential to characterise GEM detectors before their final use in the experiments.

BM@N experiment tracking system consists of Multiwire Proportional Chambers (MWPC), Gas Electron Multiplier (GEM) and Drift Chambers (DCH). It is used for trajectories reconstruction of charged particles. GEM detector is located inside the magnet and plays crucial role in track reconstruction. Algorithm of track reconstruction is described. GEM detector performance (efficiency and spatial resolution) is presented.

“…The GEM foil is optically semi-transparent due to chemical perforation by a large number of holes of about 70 µm diameter, separated by a distance of 140 µm (manufactured by CERN PH Detector Technologies (DT) and Micro-Pattern Technologies (MPT) workshop) [2]. When the GEM foil is placed between a drift cathode and a readout anode plate and a potential applied between the two sides of the foil, it behaves like a charge amplifier.…”

Abstract. BM@N is the fixed target experiment at the accelerator complex NICA-Nuclotron aimed to study nuclear matter in the relativistic heavy ion collisions. Triple-GEM detectors were identified as appropriate for the BM@N tracking system located inside the analyzing magnet. Seven GEM chambers are integrated into the BM@N experimental setup and data acquisition system. GEM construction, main characteristics and first obtained results of the GEM tracking system performance in the technical run with the deuteron beam are shortly reviewed.
