Abstract

The Position-Sensitive Detector (PSD) on base of GaAs photocathode and microchannel plate set has been developed. PSD consists of thick semiconductor photocathode with quantum e.ciency about 48% in the range of 4000-8000AA, two microchannel plates, and 16-electrode collector. The detector has spatial resolution of 20-30 microns for about 5.105 pixels, time resolution of 1 us and e.ective sensitivity up to 40%.
