摘要
一个位于韩国江原道襄阳郡地下实验室的暗物质WIMP探测实验中,采用了低能量阈高纯锗探测器,带有碘化铯晶体反符合探测器作为主动屏蔽体．整个系统设置和能量标定已经完成,并且已经积累了约155d的本底数据．还应用外置伽玛源和中子源进行了实验,以判断本底的来源．介绍了数据的分析和初步结果,并给出了实验诱人的前景。
An Ultra Low Energy HPGe （ULE-HPGe） detector, with CsI （T1） active shielding, is applied to the direct detection experiment for weakly interacting massive particles （WIMP）, and located in Korea. The setups for the whole system and the calibration have been completed and more than half a year＇s background data have been accumulated. Some external neutron and gamma source experiments were carried out to study the origin of the background. The analysis and preliminary results are shown, and an attractive future is also provided.
