We propose a transition radiation detector (TRD) prototype based on a µRGroove detector for electron/hadron separation at the EIC. The µRGroove detector is a micropattern gaseous detector (MPGD) with excellent gain uniformity, high rate capability, discharge robustness, and good spatial resolution. The TRD uses a µRGroove detector with a 10 × 10 cm² active area and a 4 cm drift gap. Signals...

Oral presentation

The Multi Wire Proportional Chambers (MWPC) have found wide application due to their ability to instrument large areas, with a rate capability of up to a few hundred kHz/cm^2. While MWPCs remain a robust solution today, their scalability is limited by the time-consuming wire-stringing process and the decreasing availability of expertise. This significantly increases production cost for large...
