Abstract

The CLEO collaboration is preparing a major upgrade of its present detector including a RICH detector for particle identification. This subdetector system follows the `proximity focussing' design and uses LiF crystal radiators and MWPCs filled with a CH₄/TEA gas mixture as photon detector. Part of the radiator crystals will have the new `sawtooth' geometry. We have constructed two of the 30 detector modules and tested these together with the first planar and `sawtooth' radiator crystals in a muon halo beam at Fermilab. For the measurement of the Cherenkov angle we obtain a single photon measurement error of 13.5 mrad for the conventional planar radiator. With 14 detected photons we find a resolution per track of 4.5 mrad. In the first measurement ever of a `sawtooth' radiator we achieve a resolution of 11.8 mrad for single photons and 4.8 mrad per track for 12.3 detected photons with a reduced geometric acceptance. These results fulfill CLEO III requirements.
