ИСТИНА

The Sarov tritium neutrino experiment is a part of the research program of the National Center for Physics and Mathematics founded in 2021. The main goals of the experiment are (i) the first observation of coherent elastic neutrino-atom scattering (CE𝜈AS) and (ii) the search for the neutrino magnetic moment using a high-intensity tritium neutrino source (at least 1 kg, and possibly up to 4 kg of tritium). A superfluid helium detector is being developed for the first observation of CE𝜈AS by 2032. It is expected to achieve the neutrino magnetic moment sensitivity which is by an order of magnitude better than the world leading constraints. The Si and CsI(pure) detectors are being developed to search for the neutrino magnetic moment with atomic ionization channel. By 2026 and 2027, they are expected to achieve the neutrino magnetic moment sensitivity which is competitive with or even better than the world leading constraints.
