Experiment on first observation of coherent elastic neutrino-nucleus scattering
The experiment on first observation of the elastic coherent scattering of neutrino off atomic nuclei is proposed with the use of the RED-100 emission two-phase xenon detector. This process was theoretically predicted more than 40 years ago but has not been observed yet. The detector has been build with the help with funding of the mega grant financial support.

The RED-100 two-phase emission detector has been built in the framework of the mega grant 11.G34.31.0049 for observation of neutrino coherent elastic scattering off atomic nuclei predicted by the Standard model. This process has not been observed yet due to lack of the detection technique of the events with the low energy deposition: the energy of nuclear recoil from the neutrino scattering in detector is in the keV- and sub-keV- energy ranges. The technology of particle detection by means of a two-phase emission detector proposed in Russia and well worked out in the experiments on search for dark matter allows one to perform this. The proposed experiment at the Kalinin nuclear power plant (KNPP) is described in this talk. The perspective of the use of such type detectors for neutrino monitoring of nuclear power reactors is considered.
