高纯锗探测器在粒子物理与天体物理中的应用

本文介绍了近年来高纯锗探测器技术的发展和新型高纯锗探测器在粒子物理、天体物理领域的应用,特别是高纯锗探测器在暗物质直接探测、双β衰变实验等极低本底的重要基础前沿研究方面的应用.中国已经建成了世界垂直岩石覆盖最深的地下实验室——中国锦屏地下实验室.中国科学家组成的CDEX研究团队拟利用吨量级的点接触电极高纯锗探测器阵列系统,在中国锦屏地下实验室开展暗物质直接实验研究,本文也介绍了这一实验计划.

The application of high purity germanium detector in particle and astroparticle physics

This article reviews the development of new technologies related with High Purity Germanium （HPGe） detector and the application of the new type HPGe detector on particle physics and astroparticle physics,especially the application of HPGe detector on the topics of ultra-low background experiments such as dark matter search experiment,double beta decay experiment and so on. China has established an underground laboratory for particle and astroparticle physics which has the deepest rock overburden in the world until now and name after China Jinping Underground Laborotory （CJPL）. CDEX collaboration in China will search directly the dark matter particle with ton-scale ultra-low threshold HPGe array detector based on the point-contact technology in CJPL. This article also gives a brief review about the CDEX collaboration.
