Description
The NEMO-3 detector aimed to study double beta (bb) decays in general
and to search for neutrinoless mode (0nbb) particularly provides
unique tracko-calorimetric technique able to register full
bb-signature. This information is crucial for investigation of
0nbb-mechanism once 0nbb-decay will be discovered. Continuing to take
data since February 2003 at the moment the NEMO-3 is the only working
bb-detector reached sub-1eV sensitivity to effective Majorana neutrino
mass, which is at level of world best 0nbb-results.
Latest 0nbb-results will be presented at the conference as well as
2nbb-results.
The goal of SuperNEMO is to reach ~50 meV sensitivity to effective
Majorana neutrino mass with 100 kg of Se-82 isotope extrapolating and
improving successful NEMO-3 technique. This sensitivity scale is the
main challenge for all leading next generation 0nbb-projects.
SuperNEMO R&D program has been started at 2006 and
currently collaboration is preparing to build first SuperNEMO module
which must demonstrate the workability of the experimental technique.
Latest R&D progress in calorimetry, tracking, low background
measurements, software will be discussed.
