【 摘 要 】

A detector of O(1 kg) modular mass with O(100 eV) threshold at O(1 kg-1keV-1day-1) background level finds tremendous application in the field of neutrino and dark matter physics. This novel detector demands overcoming several challenges at both hardware and software levels. The collaboration is exploring Germanium detection technology and highlights of the R & D program are presented. The salient features of various detector configuration and the applied analysis methodologies are discussed. In particular the differentiation of surface and bulk events by pulse shape analysis in point contact Germanium detector is described. These advances pave the way for new detector technique to be fully exploited.
