The MAJORANA Demonstrator status and prospects

The MAJORANA Collaboration is constructing the MAJORANA Demonstrator, an ultra-low background, 40-kg modular high purity Ge detector array to search for neutrinoless double beta decay in Ge-76. In view of the next generation of tonne-scale Ge-based neutrinoless double-beta decay searches that will probe the neutrino mass scale in the inverted-hierarchy region, a major goal of the Demonstrator is to demonstrate a path forward to achieving a background rate at or below 1 count/tonne/year in the 4 keV region of interest around the Q-value at 2039 keV. The P-Type Point Contact design of the Demonstrator's germanium detectors allow for significant reduction of background through pulse shape analysis. An introduction to the MAJORANA Demonstrator technical design will be given, progress of the detector's construction at the Sanford Underground Research Facility at Homestake will be highlighted, and the sensitivity of the neutrinoless double beta decay search will be discussed.
