abstract

We discuss a small-scale experiment, called $\nu$-cleus, for the first detection of coherent neutrino-nucleus scattering by probing nuclear-recoil energies down to the 10 eV-regime. The detector consists of low-threshold CaWO$_4$ and Al$_2$O$_3$ calorimeter arrays with a total mass of about 10 g and several cryogenic veto detectors operated at millikelvin temperatures. Realizing a fiducial volume and a multi-element target, the detector enables active discrimination of $\gamma$, neutron and surface backgrounds. A first prototype Al$_2$O$_3$ device, operated above ground in a setup without shielding, has achieved an energy threshold of ${\sim20}$ eV and further improvements are in reach. A sensitivity study for the detection of coherent neutrino scattering at nuclear power plants shows a unique discovery potential (5$\sigma$) within a measuring time of ${\lesssim2}$ weeks. Furthermore, a site at a thermal research reactor and the use of a radioactive neutrino source are investigated. With this technology, real-time monitoring of nuclear power plants is feasible.

    physics.ins-det 2025-05 conditional novelty 6.0 of 10

    A two-stage X-ray fluorescence source provides calibration lines from 677 eV to 8 keV, revealing a nonlinear response in a gram-scale cryogenic calorimeter.

  3. Sensitivity study of a sapphire detector using Coherent Elastic Neutrino-Nucleus Scattering process

    hep-ph 2025-02 conditional novelty 5.0 of 10

    Projected sensitivities for the proposed ICNSE sapphire detector show it could constrain new scalar and vector mediator masses at reactor sites, though its neutrino magnetic moment and weak mixing angle reach would be modest.

  4. Hunting for Axions in REactor neutrino COherent scattering Detection Experiment

    hep-ph 2025-09 conditional novelty 4.0 of 10

    RECODE, a reactor experiment with two germanium detectors, could probe axion-photon and axion-electron couplings into the cosmological triangle region at masses around 0.3 to 0.9 MeV.
