Abstract

In this study we present an UV single-photon imaging detector based on a thin-gap Resistive Plate Chamber, featuring a very good position resolution of 30 mu m in a digital readout mode and a reasonable quantum efficiency of 0.3-8% in the spectral interval 200-140nm. These detectors are inherently spark-protected and can operate without feedback problems at gas gains up to 10(5).
