Abstract
The performance of a 48 x 48 cm(2) multi-wire proportional chamber for VUV photon detection in a RICH setup is reported. The MWPC pad cathode was cove red with a solid CsI photo converter layer of 230 mu g/cm(2) thickness depo sited on a resin-stabilized graphite (RSG) coating. Cherenkov light radiate d from cosmic muons was detected in the wavelength region 160 nm < lambda < 220 nm with an average quantum efficiency of 16%. A single photo electron detection efficiency epsilon(se) > 95% and a constant long-term stability o f the photo cathode were observed. (C) 1999 Elsevier Science B.V. All right s reserved.
