Sarov Tritium Neutrino Experiment (SATURNE)
Three detectors are being developed for the goals of SATURNE:
- A 1-m3 liquid He-4 detector operating at a temperature between 40 and 60 mK is designed both to register CEνAS and to search with this
new neutrino interaction channel for the neutrino magnetic moment at a level of μν~10-13 μB, which is about an order of magnitude better
than the world-leading upper limits. Such a detector will have a rich potential to be also used for light dark matter searches with a superfluid helium target.
- A Si crystal detector with a mass from 2.9 to 5.7 kg operating at a temperature in the range of 10-50 mK and a CsI(pure)/SrI2(Eu)
scintillation
detector with a mass from 7.5 to 10.5 kg operating at a temperature between -60 and -40 oC are purposed for testing the μν value
with the elastic neutrino-electron scattering (EνES) channel on the order of ~ 10-12 μB, which is competitive with or even better than the
world-leading upper limits. Both detectors will have record low-energy thresholds for their respective types of detection systems and, upon completion of the experiment,
can be used in other areas of fundamental and applied physics, for example, in measurements of coherent elastic neutrino-nucleus scattering (CEνNS) with reactor neutrinos.
