The Cleo III Rich Detector

Abstract

CLEO III upgrade was completed with the integration of Ring Imaging CHerenkov(RICH) detector for charged particle identification. The design of this cylindrical detector consists of LiF crystal radiators and multi-wire proportional chamber photon detectors coupled through a N2 filled expansion gap. Early performance on K/pion separation is presented.
