"Beam Tests of the CLEO III LIF-TEA Ring Imaging Cherenkov Detector"


[ Full Article | Comments, Questions & Answers | Help | IIB Home Page ]


We present preliminary results from a test beam run of CLEO III RICH modules. The system consists of LiF radiators and multiwire proportional chambers containing a mixture of CH4 and TEA gases. The radiators were both flat and "sawtooth." The data were taken in a beam dump at Fermilab. We will discuss the chamber stability, electronics, the number of photons observed for both radiators, the angular resolution per photon and the angular resolution per track.
