Abstract :
A ring imaging Cherenkov counter, to be read out by four 100-channel PMTs, is a key element of the BRAHMS experiment. We report here the most recent results obtained with a prototype tested at the BNL AGS using several radiator gases, including the heavy fluorocarbon C4F10. Ring radii were measured for different particles (π−, μ−, e−) for momenta ranging from 2 to 12 GeV/c employing pure C4F10 as radiator.
