TL;DR: The Majorana experiment as mentioned in this paper 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. 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.
Abstract: 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 .

TL;DR: The MOON (Molybdenum Observatory Of Neutrinos) project aims at studies of double beta decays with a high sensitivity of m ν > ∼ 0.03 ǫ.
Abstract: The MOON (Molybdenum Observatory Of Neutrinos) project aims at studies of double beta decays with a high sensitivity of m ν > ∼ 0.03 eV and real-time studies of low-energy solar neutrinos. Two β rays from 100Mo are measured in coincidence for the 0νββ studies. The inverse β rays from solar neutrino captures of 100Mo are measured in delayed coincidence with the following β decay of 100Tc. Measurements with good energy resolution and good position resolution enable one to select true signals. A prototype MOON detector (MOON 1) is now under development. The present report describes briefly the outline of the MOON project and the status of MOON 1.

TL;DR: In this paper, the double beta (ββ ) decays with sensitivity to Majorana ν mass of the order of m ν > ∼ 0.03 ǫeV and the charged-current (CC) neutrino spectroscopy of the major components of the pp and 7 Be solar ν's.
Abstract: The MOON (Molybdenum Observatory Of Neutrinos) project aims at high sensitive studies of the double beta ( ββ ) decays with sensitivity to Majorana ν mass of the order of m ν > ∼ 0.03 eV and the charged-current (CC) neutrino spectroscopy of the major components of the pp and 7 Be solar ν 's. The present status of MOON for the low energy solar ν experiment is briefly discussed. The inverse β rays from solar- ν captures of 100 Mo are measured in delayed coincidence with the subsequent β decay of 100 Tc. MOON's exclusive CC value by 7 Be solar ν , together with the GNO CC data, will provide the pp solar ν flux with good accuracy.
