Abstract
A brief review of the history and neutrino physics of double beta decay is given. A description of the Majorana Demonstrator research and development program including background reduction techniques is presented in some detail. The application of point contact (PC) detectors to the experiment is discussed, including the effectiveness of pulse shape analysis. The predicted sensitivity of a PC detector array enriched to 86% in 76Ge is given.

The Majorana Collaboration was required to develop its own germanium purification facilities and processes for reducing the GeO2 to metal and zone refining it to a resistance of 47 Ω/cm. No experienced commercial company would reduce the enriched GeO2 nor zone-refine it. A building was rented next to Electrochemical Systems Inc., (ESI) in Oak Ridge, Tennessee, and consultants formally in the Ge industry were hired. All the required equipment was purchased and installed. This portion of the Majorana Demonstrator Project is supported by the National Science Foundation.
