SubsidieMeestersA revolutionary archaeological Pb observatory for astrophysical neutrino sources
RES-NOVA aims to revolutionize neutrino detection from supernovae using cryogenic archaeological Pb detectors, enabling precise measurements of neutrino signals and advancing multi-messenger astronomy.
Projectdetails
Introduction
One of the most energetic events in the Universe is the core-collapse Supernova (SN) where almost all the star's binding energy is released as neutrinos. These particles are direct probes of the processes occurring in the stellar core and provide unique insights into the gravitational collapse and the neutrino properties. Currently, astroparticle physics is in need of SN observations and of a detection technique highly sensitive to all neutrino flavors.
Project Overview
RES-NOVA will revolutionize how we detect neutrinos from astrophysical sources by deploying the first array of cryogenic detectors made from archaeological Pb.
Detection Mechanism
Neutrino detection in RES-NOVA is facilitated by the newly discovered Coherent Elastic neutrino-Nucleus Scattering (CEvNS). It enables the first measurement of the full SN neutrino signal, eradicating the uncertainties related to flavor oscillations.
Advantages of CEvNS
To fully exploit the advantages of CEvNS, 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.
Innovative Approach
The unconventional approach of RES-NOVA is to use ultra-pure archaeological Pb and run it as a cryogenic detector with:
- Low-energy threshold (<1 keV)
- Unprecedented background (<0.001 c/ton/keV/s)
These features also open new opportunities in multi-messenger astronomy, Dark Matter, and neutrino property studies. The success of my pioneer work in operating archaeological Pb-based cryogenic detectors is pivotal for RES-NOVA realization.
Survey Capabilities
RES-NOVA will survey 90% of the potential galactic SNe, with only a total detector volume of (30 cm)^3. Future detector upgrades will enhance our SN sensitivity into the uncharted territory >1 Mpc and increase the SN observation rate.
Future Prospects
RES-NOVA has the potential to lay the foundations for a future generation of European neutrino telescopes, as all its SN neutrino detectors are currently going offline.
