Description
Coherent elastic neutrino nucleus scattering (CE$\nu$NS) offers a unique way to study neutrino properties and to search for new physics beyond the Standard Model. The NUCLEUS experiment aims to measure CE$\nu$NS of reactor anti-neutrinos down to unprecedented low nuclear recoil energies. The novel gram-scale fiducial-volume cryogenic detectors feature an ultra-low energy threshold of $\sim$20 eV in nuclear recoil and a rise time of a few 100 $\mu$s which allows the operation above ground. The fiducialization of the detectors provides an effective discrimination of ambient $\gamma$- and surface backgrounds. Furthermore, the use of multiple targets promises a high physics potential.
The NUCLEUS experiment will be located at a new experimental site at the Chooz nuclear power plant in France, providing a high average anti-neutrino flux of $1.7\cdot10^{12}\,\bar{\nu_e}/(\text{s}\cdot\text{cm}^2)$. The commissioning of the full experimental setup is planned for 2022. This talk will review the physics potential of NUCLEUS and its current status.
