    "abstract": "A Ring Imaging \\v{C}erenkov detector built for the BRAHMS experiment at the\nBrookhaven RHIC is described. This detector has a high index of refraction gas\nradiator. \\v{C}erenkov light is focused on a photo-multiplier based photon\ndetector with a large spherical mirror. The combination of momentum and ring\nradius measurement provides particle identification from 2.5 GeV/c up to 35\nGeV/c for pions and kaons and well above 40 GeV/c for protons during runs that\nhad the radiator index of refraction set at $n-1=1700 \\times 10^{-6}$.",
