Scientists Detect Elusive Neutrinos Near Reactor After 50-Year Quest

Quick summary:

• Neutrinos and Antineutrinos: Neutrinos are elusive particles that interact minimally with matter, making detection challenging.Scientists successfully detected antineutrinos from a nuclear reactor using the CONUS+ experiment with a small 3 kg detector.
• Relocation and Development: The CONUS experiment was moved to the Leibstadt nuclear power plant in Switzerland in mid-2023. Improved detectors enabled measuring Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) at lower energy levels.
• unique insights: CEvNS involves neutrinos interacting coherently with atomic nuclei, increasing detection probability.395±106 neutrino signals were detected over 119 days of measurement, aligning closely with theoretical predictions.
• Scientific Significance: This marks the first observation of CEvNS at full coherence and lower energies in a reactor setup.
• Applications and Future Potential: The technology could lead to mobile detectors for reactor monitoring or isotope analysis. Enhanced detectors introduced in autumn 2024 aim to improve accuracy for exploring new physics beyond the Standard Model.
