Аннотация:SATURNE is the Sarov tritium neutrino experiment that aims at the first observation of coherent elastic neutrino–atom scattering and the search for neutrino electromagnetic properties. A marked feature of the experiment is the use of a high-intensity tritium source of electron antineutrinos with a total tritium mass of at least 1 kg (10 MCi). Three detectors are being developed for the goals of the experiment. A 1-m3 liquid He-4 detector operating at a temperature between 40 and 60 mK is designed both to register coherent elastic neutrino–atom scattering and to search for the neutrino magnetic moment at a level of μ_ν ∼ 10^{−13} μ_B, which is about an order of magnitude better than the world-leading upper limits on the μν value. A 4-kg Si crystal detector operating at a temperature in the range of 10–50 mK and a 14-kg SrI_2(Eu) scintillation detector operating at a temperature between −60 and −40 ◦C are purposed for testing the μν value on the order of ∼ 10^{−12} μ_B, which is competitive with or even better than the world leading upper limits.
