Building a 0{nu}{beta}{beta} experiment with the ability to probe neutrino mass in the inverted hierarchy region requires the combination of a large detector mass sensitive to 0{nu}{beta}{beta}, on the order of 1 ton, and unprecedented background levels, on the order of or less than 1 count per year in the 0{nu}{beta}{beta} signal region. The MAJORANA Collaboration proposes a design based on using high-purity enriched {sup 76}Ge crystals deployed in ultra-low background electroformed Cu cryostats and using modern analysis techniques that should be capable of reaching the required sensitivity while also being scalable to a 1-ton size. To demonstrate feasibility, the collaboration plans to construct a prototype system, the MAJORANA Demonstrator, consisting of 30 kg of 86% enriched {sup 76}Ge detectors and 30 kg of natural or isotope-76-depleted Ge detectors. We plan to deploy and evaluate two different Ge detector technologies, one based on a p-type configuration and the other on n-type.
