Abstract
A microstrip gas chamber (MSGC) with a semi-transparent CsI photon con verter for the detection of single VUV photons is described. The detec tor is sensitive to photons in the wavelength region 160 nm < lambda < 220 nm and is operated with Ar-C4H10, (90-10) as detector gas at p = 1000 mbar with a gain g similar or equal to 3 x 10(4). The back electr ode of the MSGC is formed by a pad array allowing for two-dimensional position determination of the incident photon. For single VUV photons at lambda similar or equal to 172 nm a detection efficiency epsilon(to t) similar or equal to 9% with anode readout and epsilon(tot) similar or equal to 3.5% with pad readout could be achieved.
