| 摘 要： | A prototype of multi-gap resistive plate chamber （MRPC） modules with 6 gas gaps of 220 μtm used for the time-of-flight （TOF） detectors has been developed by STAR TOF group. A tray （TOFr） composed of 28 MRPC modules was constructed and operated in STAR for the d＋Au collisions and Au＋Au collisions during 2003 RHIC and 2004 RHIC run. Results show its time resolution is 85 ps with the average efficiency of 95% and clear identification of K/π up to 1.6 GeV and proton/K up to 3.0 GeV.
