Abstract

Having the merits of low capacitance and low energy threshold, PC-HPGe (Point-Contact High Purity Germanium) detector has been proposed for the direct WIMP (Weakly Interacting Massive Particle) searches in CDEX (China Dark matter Experiment), which is located in CJPL (China Jing Ping underground Laboratory) with a rock overburden of about 2400 m. Intensive studies are underway to fully understand this detector´s working principle and to fully explore its capability. By using Maxwell 3D, MaGe and Geant4, some basic characteristics of PC-HPGe were simulated and presented here.
