Abstract

Multi-gap Resistive Plate Chamber (MRPC), which has excellent performance and relatively low cost per channel, is a good candidate for Time-of-Flight (TOF) system in modern high energy physics experiments. A new kind of MRPC, Long-strip MRPC (LMRPC) with 50 cm × 2.5 cm strips, was tested at GSI-FOPI with secondary beam. The resets show that this LMRPC prototype can achieve 60 to 70 ps σ time resolution and greater than 97% detecting efficiency. The cross talk between readout strips is less than 2%. The measured spatial resolution along the strips is about 0.36 cm σ.

长条MRPC的研发

多间隙电阻板腔(MRPC)具有优异的性能和较低的单通道成本，是现代高能物理实验中飞行时间(TOF)系统的理想选择。在二次光束的GSI-FOPI下，对一种新型MRPC——50 cm × 2.5 cm长条MRPC (LMRPC)进行了测试。实验结果表明，该LMRPC样机可以达到60 ~ 70 ps σ的时间分辨率，检测效率大于97%。读出条之间的串扰小于2%。测得的空间分辨率约为0.36 cm σ。
