Fabrication of Ge detector with the USD-grown crystals at LBNL

POSTER

Abstract

P-type point contact (PPC) High purity germanium (HPGe) detectors are widely used in dark matter and neutrino experiments such as CDEX, TEXONO, CoGeNT, COHERENT, GERDA and Majorana, etc.. In order to understand and improve the performance of PPC detectors at various environmental and system configurations in a convenient and economic way, we are in the process of fabricating a few mini-PPC detectors. This way we avoid risking expensive PPC detectors in unconventional operating environments. We take advantage of resources, facilities and equipment at both USD and Lawrence-Berkeley National Lab. The first mini-PPC detector is expected to be fabricated in the summer 2019.
