The Cerenkov Ring-Imaging Detector: Recent Progress and Future Development
Abstract
Results are reported on measurements of Cerenkov ring images using a multistage MWPC with an argon-TEA gas mixture. A specific detector response of N0 = 56 cm-1 was obtained. It is shown that with some minor modifications to the detector, this value can be raised to N0 = 90 cm-1. Using an argon-methane-TEA mixture in the MWPC, it is shown that efficient single-photoelectron detection can be achieved with proportional wire amplification without preamplification. A design of a new type of drift chamber (TPC) detector for two-dimensional measurement of the ring image is described. The use of the Cerenkov ring-imaging tecnique in high-energy physics experimentation is discussed, and in particular a full solid-angle detector for LEP is suggested.
