Abstract
We present the result of a systematic investigation of the quantum eff iciency of reflective CsI photocathodes in the spectral range 140-220 nm. Powder and crystal forms of CsI were used for evaporation of bulk and porous photocathodes. The measurements were made without gaseous a mplification in vacuum and in methane. The results of radiation resist ance measurements at doses reaching 4500 Gy are also reported.
