Abstract
A fast RICH prototype with a CsI photocathode has been built. The quan tum efficiency has been estimated by two independent techniques: a UV lamp measurement and a detection of Cherenkov light produced in a liqu id radiator. The crucial influence of the photocathode substrate on th e quantum yield is demonstrated in this paper. The results obtained wi th our prototype have been used to simulate the performances of a Fast RICH for a B meson factory.
