| 摘 要： | CDEX(China Dark matter EXperiment)合作组将在中国锦屏极深地下实验室(CJPL China Jin-Ping deep underground Laboratory)利用极低能阈高纯锗(ULE-HPGe)探测器进行暗物质的直接探测。在地下实验之前,对CsI(Tl)晶体反符合探测器进行了地面的实验研究。主要包括光导的选择,光反射层的选择,CsI(Tl)晶体的高度一致性测试,不同侧面非均匀性的测试,以及所有晶体的测试结果。通过地面实验的前期工作,我们对反符合探测器有了一定认识,为地下实验做了准备。

| Abstract: | CDEX(China Dark matter EXperiment) Collaboration will carry out direct search for dark matter with Ultra-Low Energy Threshold High Purity Germanium(ULE-HPGe) detector at CJPL(China Jinping deep underground Laboratory).Before underground research,some experiments of the CsI(Tl) crystal Anti-Compton detector have been done on the ground,including light guide choice,wrapping material choice,height uniformity of CsI(Tl) crystal,side uniformity of CsI(Tl) crystal and the test results of all the crystals.Through the preliminary work on the ground,we have got some knowledge of the anti-compton detector and prepared for the underground experiment. |
