Description

We present latest results of a micro-hole and strip plate (MHSP) electron multiplier operating in pure xenon at atmospheric pressure. We report on avalanche gain of ~2×104, stable within ~3% after an accumulated charge of 4 [mu]C/mm2, when irradiated with 0.5 kHz/mm2 5.9 keV photons. No photon-induced secondary effects or discharges have been observed at this gain. An energy resolution of 14% was obtained with 5.9 keV X-rays. http://www.sciencedirect.com/science/article/B6TJM-4GPVP8N-4/1/8f46f4fef69febd247768213084b087b
