Efficiency and High Rate Performance of the TRT

The efficiency for correctly observing a signal event in a TRT end-cap sector prototype is measured as a function of the background rate. The impact on the results of both the signal and background pulse shapes is studied using electronically generated pulses. The results are then related to similar...

Sumario:The efficiency for correctly observing a signal event in a TRT end-cap sector prototype is measured as a function of the background rate. The impact on the results of both the signal and background pulse shapes is studied using electronically generated pulses. The results are then related to similar test beam data, and it is shown, that the efficiency can be adequately measured in the system-test laboratory using electronically generated pulses. Previous discrepancies between test-beam results and recent data acquired using a photon source in Israel are explained by the different energy spectra of the background pulses.
