Issues addressed and main goals of research:
Search for and investigation of double-neutrino and neutrinoless modes of double beta-decay, clarification of the neutrino nature, Majorana or Dirac, and 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, and search for exotic particles (monopoles). Use of the neutrino detector for a distant investigation of processes inside of the reactor core of the Kalinin Nuclear Power Plant. Search for sterile neutrinos. Spectroscopy of nuclei far from stability. Development of new methods for charged and neutral particle detection.

Expected results in the current year:
  • Data taking in the 2 0-decay measurements of 106Cd, 82Se, 150Nd, 76Ge with the SuperNEMO and GERDA spectrometers.

  • Processing of experimental data and determination of T1/2(22) for 48Ca, 96Zr, 130Te, 116Cd, 150Nd, 82Se and 76Ge.

  • Data taking with the HPGe-based low-background spectrometer at the Kalinin Nuclear Power Plant. Search for a signal of coherent neutrino scattering on the Germanium nuclei. Search for the neutrino magnetic moment at the sensitivity level of ~ 10 -12 µB.

  • Continuation of data taking in the EDELWEISS experiment with new detectors operating with an energy threshold of 0.3 keV suitable for the extra-low mass WIMP region. Analysis of previously accumulated data, determination of parameters for light dark matter for the mass region below 1 GeV/c 2.

  • Research and development of the semiconductor-based detecting systems for the GERDA and MAJORANA experiments. Continuation of the data taking in both experiments.

  • Data taking and development of the 6th and 7th clusters of the Baikal-GVD telescope (Baikal project).

  • Investigation of KLL and KMM Auger electrons in 67Ga and 152,154,155Eu decays.

  • Development and testing of new low-threshold (~ 200 eV) HPGe detectors for searching for the coherent neutrino scattering, as well as plastic scintillator detectors for their active shielding.

  • Testing of certain systems of the DANSS neutrino detector. Data taking in order to search for the sterile neutrino. Data analysis and publication. Development of the industrial reactor monitoring with the DANSS spectrometer.
