Abstract
Possibilities of NEMO technique for future neutrinoless double-beta-decay experiments are discussed. Main idea is to have a realistic project with planned sensitivity for half-life on the level ≈ (1-2) × 1026 y (sensitivity to neutrino mass ≈ (0.05-0.1) eV). It is demonstrated that this can be achieved using improved NEMO technique to investigate 100 kg of 82Se. Possible improvements of NEMO technique and background conditions are discussed. Scheme of future SUPERNEMO detector and main characteristics of experiment are presented. Such detector can be used also to investigate 0νββ decay in 100Mo, 130Te and 116Cd with sensitivity up to ≈ (5-10)×1025 y (or with sensitivity to neutrino mass ≈ 0.1 eV).
