Abstract: (Elsevier)
The proposed Majorana experiment is based on an array of segmented intrinsic Ge detectors with a total mass of 500 kg of Ge isotopically enriched to 86% in 76 Ge. Background reduction will be accomplished by: material selection, detector segmentation, pulse shape analysis, electro-formation of copper parts, and granularity of detector spacing. The predicted experimental sensitivity for measurement of the neutrinoless double-beta decay mode of 76 Ge, over a data acquisition period of 5000 kg·y, is T 1 / 2 0 ν ∼ 4 × 10 27 y .References(4)
