Abstract
A novel, fast, hadron-blind imaging TRD is proposed. Traditonal radiators are followed by novel, particle-blind photon imaging detectors, combining thin Csl photon convertors and fast gaseous electron multipliers. The expected performance of the TRD, based on multiple radiator/detector elements, is simulated, using experimental and theoretical data of the photon detector characteristics. Such TRDs can provide 100 GeV electron detection efficiency above 90% with hadronic background rejection factors of 10 2 – 10 4 . The nanosecond timing, very low occupancy and the high rate capability make these devices very competitive tools for ultrarelativistic electron identification under critical conditions expected in future particle physics experiments.
