用于暗物质间接测量外围反符合探测器的读出研究

The Research of Anti-coincidence Scintillator Detector Readout for Dark Matter Detection

在暗物质的间接探测中,需要利用反符合探测器对带电粒子进行定位标记,研究了在截面为1 cm2,长为80 cm的塑料闪烁条中插入直径1 mm的波移剂光纤并用盖革模式雪崩光二极管读出的实验方案。宇宙线测试结果表明此种实验方案具有很高的探测效率,以及较好的读出均匀性。

In the indirect detection of dark matter, Anti-coincidence detector is needed for marking charged particles. It present a method, using plastic scintillator bar（80 cm× 1 cm^2） with WLS fiber and MPPC readout. Cosmic ray test results show the high efficiency and better uniformity.
