Abstract
The Omega RICH, a large-aperture detector for identification of secondary p ions, kaons, and (anti) protons was in operation at the CERN Omega spectrom eter facility between 1984 and 1994. Cherenkov photons from a 5 m long radi ator were detected in drift chambers with quartz windows, using TMAE-loaded counting gases. The RICH was used by experiments WA69 and WA82, until 1988 . It was then equipped with new drift chambers and mirrors and was in use s ince 1990 in experiments WA89 and WA94. The setup in the WA89 hyperon beam experiment is described in more detail and efficiencies, resolutions, and p hysics results are discussed. (C) 1999 Elsevier Science B.V. All rights res erved.
