The Majorana Demonstrator: A search for neutrinoless double-beta decay of germanium-76


Conference Paper

The observation of neutrinoless double-beta decay would determine whether the neutrino is a Majorana particle and provide information on the absolute scale of neutrino mass. The Majorana Collaboration is constructing the Demonstrator, an array of germanium detectors, to search for neutrinoless double-beta decay of 76Ge. The Demonstrator will contain 40kg of germanium; up to 30kg will be enriched to 86 in 76Ge. The Demonstrator will be deployed deep underground in an ultra-low-background shielded environment. Operation of the Demonstrator aims to determine whether a future tonne-scale germanium experiment can achieve a background goal of one count per tonne-year in a 4-keV region of interest around the 76Ge neutrinoless double-beta decay Q-value of 2039 keV. © 2012 American Institute of Physics.
