摘要
介绍了具有 6层气隙的电阻板室的结构和工作原理 .用动量 7GeV c的粒子束测量了该探测器的性能 ,得到时间分辨为 60— 70ps ,探测效率大于 97% .在动量为 3GeV c的正电荷粒子束流测试中 ,用该探测器获得了p和π的时间谱 ,实现了很好的粒子分辨 .
The structure and working principle of a six-gap resistive plate chamber is discussed. A π-beam with a momentum of 7GeV/c is used to test this detector,and a time resolution between 60 and 70ps is obtained. The detection efficiency is greater than 97%. In the test with a 3GeV/c beam of positive particles,this detector got a clear separation between p/π particles.
