Description
The NUCLEUS experiment aims at a high-precision measurement of the coherent elastic neutrino-nucleus scattering (CEνNS). This process is a unique tool to search for new physics beyond the Standard Model and to understand the properties of its most elusive particles, neutrinos.
NUCLEUS will use CaWO4 and Al2O3 cryogenic detectors to perform precision measurements of CEvNS at unprecedentedly low energies. It is based on recently demonstrated cryogenic detectors with nuclear-recoil energy thresholds in the 20eV regime. After commissioning at TUM in 2021, the experiment will be assembled at a new shallow site, the Very Near Site, in between the two 4.25GW reactor cores of the CHOOZ B nuclear power plant in France. NUCLEUS plans to start its first phase in late 2022 and to obtain a measurement of the process with 10g target in 1 year of data taking, thanks to the high cross-section of CEvNS. In this talk, the design, the current status and the expected sensitivity of the experiment are presented.
