Abstract
High Energy Physics experiments are currently entering a new era which requires the operation of gaseous particle detectors at unprecedented high rates and integrated particle fluxes. Gas Electron Multiplier (GEM) introduced in 1997, constitutes a powerful addition to the family of fast radiation detectors. They allow to achieve both excellent localization accuracy and high rate capability that make this technology attractive for charged particle tracking at high luminosity colliders. Improvements in the performance of the GEM detectors were achieved by stacking more than one GEM foil inside the detector. A summary of the studies performed on \(10\,\mathrm{cm} \times 10\,\mathrm{cm}\) Triple GEM detector and its performance is presented. We also report on performance of the \(100\,\mathrm{cm} \times 45\,\mathrm{cm} \times 22\,\mathrm{cm}\) GEM detector such as GEM foil leakage currents, high voltage circuit performance, and effective gain. Along with that we describe some studies related to gas purity using Gas Chromatograph.
