The field of ring imaging (broad band differential) Cherenkov detectorsl has become a very active area of interest in detector development at several high energy physics laboratories. Our group has previously report-ed2 on a method of Cherenkov ring imaging for a counter with large momentum and angular acceptance using standard photo multipliers. Recently, we have applied this technique to the design of a set of Cherenkov counters for use in a particle search experiment at Fermi National Accelerator Laboratory (FNAL). This new detector operates over the range 0.998 < β < 1.000 in velocity with a δβ ~ 2 x 10-4. The acceptance in angle is ± 14 mrad in the horizontal and ± 28 mrad in the vertical. We report here on the performance of this counter. Copyright © 1981 by The Institute of Electrical and Electronics Engineers, Inc.
