Study on the performance of multi-gap resistive plate chambers

A kind of multi-gap resistive plate chamber (MRPC) was developed for the STAR experiment at RHIC. The MRPC has excellent time resolution with high efficiency and can be used as the time-of-flight detector. In this paper, we present some performance of MRPC tested by cosmic ray, and performances of MRPC working in different gas mixture and in different temperature are also illustrated.
