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 (KNPP). 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 2b0n decay measurements of 106Cd, 82Se, with the SuperNEMO spectrometer. Processing of the data collected in the GERDA experiment, set T1/2 limits for different 2b-decay modes.
- Processing of experimental data and determination of T1/2(2b2n) for 48Ca, 96Zr, 130Te, 116Cd, 82Se and 76Ge.
- Data taking with the HPGe-based low-background nGeN spectrometer at the Kalinin Nuclear Power Plant. Search for a signal of coherent neutrino scattering on the germanium nuclei. Data taking start searching for the neutrino magnetic moment at the sensitivity level of ~ (5-9)·10 -12 µB after several years of data taking.
- Continuation of data taking in the EDELWEISS experiment with new detectors operating with an energy threshold of 0.1 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. Start of the Ricochet phase of the experiment for precision CEnNS studuing at ILL with the detectors developed by EDELWEISS.
- Start of data taking in the tone-scale LEGEND experiment, searching for 2b2n decay of 76Ge.
- Data taking with eight clusters of the BAIKAL-GVD neutrino telescope. Search for and study of high-energy neutrinos of the astrophysical nature. Constructing and commissioning of new detector clusters. Development and testing of new data acquisition and data transmission systems aiming at a lower energy threshold (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 of plastic scintillator detectors for their active shielding.
- Results of search for sterile neutrinos on the 2016-2021 data accumulated by the DANSS spectrometer. Precision estimates of the gamma and neutron background at the location of the DANSS spectrometer (room A336 under the reactor of the 4th power unit of the KNPP). R&D results of the spectrometr modernization.
- The radiochemical laboratory of the 2nd class will be commissioned in the DLNP; equipment for the manufacture of radioactive sources for brachytherapy of cancer diseases will be installed; important work for obtaining of a sanitary and epidemiological certificates for the radiochemical laboratory will be concluded.
- Continuation of the MONUMENT project. Preparation for 2022 PSI accelerator run (purchasing of detectors and targets, update of the cryostats). Data taking. Analysis of previously accumulated data.
