Leaders:

V.B. Brudanin
A. Kovalik

Participating Countries, Institutes and International organizations:
Armenia, Belarus, Belgium, Bulgaria, Czech Republic, Finland, France, Germany, Kazakhstan, Mongolia, Poland, Romania, Russia, Slovak Republic, Ukraine, USA, Uzbekistan.
Scientific Programme:
Search for and investigation of double-neutrino and neutrinoless modes of double beta-decay, clarification of the Majorana neutrino nature, absolute neutrino mass scale and hierarchies. Search for the neutrino magnetic moment and dark matter. Investigation of galactic and extragalactic neutrino sources, diffusive neutrino cosmic background, search for exotic particles (monopoles). Study of dd and pd reactions at ultra low energy by means of plasma accelerators and different targets; development of diagnostics methods for the dynamics of dense plasma flux formation. Spectroscopy of nuclei far from stability. Development of new methods for charged and neutral particle detection.

Expected main results in 2012:

Data taking in the 2-decay measurements of ¹⁵⁰Nd, ¹¹⁶Cd, ¹⁰⁶Cd, ¹⁰⁰Mo, ⁹⁶Zr, ⁸²Se, ⁴⁸Ca with the NEMO and TGV spectrometers.
Processing of experimental data and determination of T_1/2(22) for ⁴⁸Ca and ¹⁰⁶Cd.
Data taking with the GEMMA-II spectrometer at the Kalinin Nuclear Power Plant; getting an upper limit for the neutrino magnetic moment at the level of ~ 10 ^-12 µ _B.
Low-background physics run with the setup consisting of 28 HPGe bolometers with the total weight of about 10 kg will be continued. At this stage of EDELWEISS-II the aim is to reach a sensitivity of 5 · 10 ^-7 pb to the WIMP nucleon cross section for a WIMP mass of 100 GeV.
Research and development of the semiconductor-based detecting systems for the GERDA and MAJORANA experiments. Beginning of data taking in the experiment on the search for the ⁷⁶Ge 2 0-decay.
Mounting of the NT1000 prototype string. Data taking and extraction of physical results with the NT200+ spectrometer.
Investigation of the astrophysical S-factor and effective dd cross section in the 2-7 keV impact energy for the D₂O target.
Investigation of KLL and KMM Auger electrons in ⁶⁵Zn, ⁶⁷Cu, ⁶⁷Ga and ^152,154,155Eu decays.
Design and creation of the low-threshold (~ 200 eV) HPGe detector. Production of low-background plastic scintillators for the Super NEMO experiment.
Design and creation of the reactor antineutrino detector DANSS.
