摘要
介绍了可用于粒子探测的大面积玻璃高阻板探测器RPC(ResistivePlateChamber) .使用两块间隔 2mm的普通浮法玻璃作为电极 ,其中充入流动的混合气体 (氩气 +异丁烷 +F134A) ,工作高压约 96 0 0V ;性能测试结果 ,其单室效率可达 97% ,时间分辨可达到 1.8ns .
A RPC (resistive plate chamber) prototype made with domestic glass is tested, which is suitable for large area particle detection. The constituent elements are two parallel glass plates with 2mm gas gap. A gas mixture of Argon, Iso-butane and F134A is utilized. Test results show that the chamber efficiency is 97% and time resolution is 1.8ns at an operating voltage 9600V, it has a relatively lower single rates than a normal bakelite chamber. Except for the dead regions caused by the spacers and frame, the efficiencies from different strips in the same readout plate show good consistency. The technological design for mass production for this glass RPC is under investigation.
