The MAJORANA 76Ge neutrino less double-beta decay project: A brief update

Understand

At present, MAJORANA is a research and development (R&D) project to investigate the feasibility and cost of constructing and operating a one ton decay experiment with ~1000 kg of Ge detectors fabricated from germanium enriched to 86% in .

• The study will include three separate cryostats with various types of detectors: un-segmented, un-segmented point-contact, minimally segmented, and highly segmented.
• One cryostat will contain at least 30 kg of enriched (preferably point-contact) detectors.
• The performance of the cryostats and detectors as well as background levels will be investigated.
