| Publication Abstract: | Transition Radiation Detectors (TRD) has the attractive feature separating particles by their gamma factor. The classical TRDs are based on Multi-Wire Proportional Chambers (MWPC) or straw tubes, using a Xenon based gas mixture to efficiently absorb transition radiation photons. %While it works for These detectors operate well in experiments with relatively low particle multiplicity. The performance of MWPC-TRD in experiments with luminosity of order $10^{34} cm^2s^{-1}$ and above, is significantly deteriorated due to the high particle multiplicity and channel occupancy. Replacing MWPC or straw tubes with a high granularity Micro Pattern Gas Detectors (MPGD) like Gas Electron Multipliers (GEMs), could improve the performance of the TRD. In addition, GEM technology allows to combine a high precision tracker with TRD identificator. This report presents a new TRD development based on GEM technology for the future Electron Ion Collider (EIC). A first beam test was performed at Jefferson Lab (Hall-D) using 3-6 GeV electrons. A GEM-TRD module has been exposed to electrons with and without a fiber radiator. First results of test beam measurements and comparison with Geant4 Monte Carlo will be presented. |
