Description

Germanium detectors with sub-keV sensitivities [1] offer a unique opportunity to search for light WIMP Dark Matter and axion-like particles. We will highlight our results and status of CDEX dark matter experiment [2] at the China Jinping Underground Laboratory (CJPL) [3] in China. The detector R&D programs which allow us to experimentally probe this new energy window will be discussed, especially the new bulk/surface events separation scheme. Recent results from axion searches, as well as results from non-modulated and modulated dark matter searches [2] will be described. Status of the construction of CJPL-II will be presented. [1] H. B.
