Аннотация:A description of an experimental scheme for the study of coherent elastic neutrino–atom scattering using a tritium neutrino source and superfluid He-4 detector is given. The basic concept was originally proposed in our paper in 2019 and its realization has a potential to provide a new record upper limit on the neutrino magnetic moment at a level of below 10^{−12} μ_B. It is currently implemented in the Sarov tritium neutrino experiment (SATURNE), which is under preparation and will employ a high-intensity tritium neutrino source with activity of 10 MCi or even 40 MCi.
