Description
Gas Electron Multiplier (GEM) is a cutting edge Micro Pattern Gaseous detector (MPGD) technology suitable as tracking device in high rate Heavy-Ion (HI) experiments for their high rate handling capability and good spatial resolution. The performance studies including the detector efficiency, gain, energy resolution and also the long-term stability study under high radiation are the most important aspects need to be investigated before using the detector in any experiments. In this work all of the above mentioned aspects are investigated for a single mask triple GEM chamber prototype operated with premixed Ar/CO$_2$ gas mixtures using a 5.9 keV $^{55}Fe$ X-ray source. The gain and energy resolution are corrected for the variation of ambient temperature/pressure ratio (T/p). The effect of the variation of bias current on the performance of the detector is also studied. The details of the experimental setup, methodology, and results will be discussed.
