Abstract :
A prototype 168-channel multi-gap resistive plate chamber (MRPC) time-of-flight system for the STAR experiment at RHIC was completed in February 2002, tested for 10 weeks at the AGS at BNL, and installed in the STAR detector for the 2002–2003 physics run. At the AGS, the MRPC detectors were operated on a number of different gas mixtures, high voltages, and threshold voltages. The results for detection efficiency, time resolution, streamer probability, and noise rates are presented.
