Abstract. :. We are developing a new photon detector with gas amplification devices. A semitransparent CsI photocathode is combined with 10cm×10cm GEM/μPIC for the first prototype which is aimed for the large liquid Xe detectors. Using Ar+C. Load lock gun worked very well in the Test Cave, with very good photocathode lifetime.. Once installed in CEBAF (7/07) the gun functioned well, but with very poor lifetime..
