Dr Anthony Onillon (CEA)


Coherent elastic neutrino-nucleus scattering (CEνNS) offers a unique way to study neutrino properties and to search for new physics beyond the Standard Model.

The NUCLEUS experiment aims at measuring the CEνNS signal from reactor antineutrinos. The detector will consist of a newly developed 10 g target array of CaWO4 and Al2O3 cryogenic calorimeters with demonstrated ultra-low threshold of ~20 eV, an energy region never explored so far. The experiment will be installed between the two pressurized water reactors of the Chooz B power plant in the French Ardennes. Currently, the experiment is under construction and the commissioning of the full apparatus is expected to start in 2022.

This talk will present the expected sensitivity of the NUCLEUS experiment to the CEνNS signal as well as its physics potential. The current status and the next steps of the experiment will be reported.
