【摘要】 主要讨论了用于STAR TOFTray的 6层气隙 6× 1读出单元的电阻板室的工作原理 ;用宇宙线测量系统得到MRPC时间分辨 <80ps ,噪声低于 5Hz/pad ,小幅度信号所占的比例 >95%.所有的测试都是对一个特定的室 (J 1 8)进行的 .宇宙线测量系统的时间晃动为 79.5ps .更多还原

【Abstract】 Cosmic ray test results of a six gaps multi gap resistive plate chambers (MRPCs) are reported in detail. All the tests are processed on a chamber named J 18. The time resolution is better than 80 ps with the noise being below 5 Hz/pad and the ratio of small signals being greater than 95 per cent of all the signals. The time jetter of the cosmic ray detecting system is 79.5 ps.更多还原
