Background Mitigation in a Highly-Segmented HPGe Detector

POSTER

Abstract

We present the first study of a highly-segmented HPGe detector with pulse shape discrimination in a low background environment. The detector consists of a 8x5 highly-segmented HPGe crystal, shielded with 5 cm of normal lead. Data was collected at the Oroville low-background facility to study backgrounds applicable to the proposed Majorana neutrinoless double-beta decay experiment. An analysis of the efficiency of highly-segmented detectors to eliminate these backgrounds will be presented.
