The Position-Sensitive Detector (PSD) on base of GaAs photocathode and microchannel plate set has been developed. PSD consists of thick semi-conductor photocathode with quantum efficiency about 48% in the range of 4000-7500 A, two micro-channel plates, and 16-electrode collector. The detector has spatial resolution of 20-40 microns for about 5102 pixels, time resolution of 1 μs and effective sensitivity up to 35%.
