摘　　要：在实验室内建立了一套宇宙线测试系统(CORTS),并对一个大面积CMSRE1/2RPC的完整样品进行了系统的测试.结果为RPC的探测效率约85%,时间分辨率为0.87±0.08ns,空间分辨本领为1.5根读出条宽度,与CERN束流测试中得到的数据基本吻合.对比表明采用宇宙线测试可以可靠地获得若干关键的RPC探测器性能指标.A cosmic-ray testing station (CORTS) in laboratory has been installed, and the performance of a prototype of CMS RE1/2 RPC was tested. The RPC's efficiency is about 85%, the time resolution is 0.87±0.08ns, and the spatial resolution is 1.5 times the width of read-out strip, which are consistent with the results obtained using the muon beam at CERN. The comparison makes clear that cosmic-ray test can provide reliably the basic parameters which describe the RPC performance.
