Abstract

A Ring Imaging Cherenkov detector built for the BRAHMS experiment at the Brookhaven RHIC is described. This detector has a high index of refraction gas radiator. Cherenkov light is focused on a photo-multiplier based photon detector with a large spherical mirror. The combination of momentum and ring radius measurement provides particle identification from 2.5 to 35 GeV/c for pions and kaons and well above 40 GeV/c   for protons during runs that had the radiator index of refraction set at n-1=1700×10-6n-1=1700×10-6.
