The MAJORANA Low-Background Broad Energy Germanium Detector

Abstract:  The MAJORANA DEMONSTRATOR is an array of natural and enriched high purity germanium detectors that will search for the neutrinoless double-beta decay of 76-Ge. As part of the MAJORANA research and development efforts, we have deployed a modified, low-background broad energy germanium detector at the Kimballton Underground Research Facility. With its sub-keV energy threshold, this detector is potentially sensitive to non-Standard Model physics, including interactions with WIMPs.

Dr. Giovanetti will discuss detector backgrounds in the WIMP region of interest, present results from 221 days of exposure, and explore the implications and outlook for the MAJORANA DEMONSTRATOR.
