Thanks to the Seed-Money funding (2020-1), we were able to demonstrate the proof of principle of the RES-NOVA project. RES-NOVA will detect neutrinos from astrophysical sources by deploying the first array of cryogenic detectors made from archaeological Pb.
Neutrino detection in RES-NOVA is facilitated by the newly discovered Coherent Elastic neutrino-Nucleus Scattering (CE$\nu$NS). It enables the first measurement of the full SN neutrino signal, eradicating the uncertainties related to flavor oscillations. To fully exploit the advantages of CE$\nu$NS, RES-NOVA ennobles Pb from being a passive shielding to the most sensitive detector component. Pb has the highest cross-section, 10$^4$ times higher than all used detection channels, enabling the deployment of a cm-scale neutrino observatory. Its archaeological origin makes it suitable for the operation in ultra-low background condition, thus enhancing RES-NOVA sensitivity.
In this talk we will outline the potential of RES-NOVA as a future next generation SN neutrino observatory, and we will present the first results from a small scale proof of principle.
