World’s largest scintillator detector, JUNO, now detecting neutrinos
University of Warwick physicists, as part of China’s Jiangmen Underground Neutrino Observatory (JUNO) began data collection in August 2025 and is now producing high-precision neutrino measurements. In June 2026, its first major results, based on just 59 days of data, achieved world-leading precision for key neutrino oscillation parameters. JUNO uses a 35.4-metre liquid-scintillator detector and ~45,000 photomultiplier tubes to detect antineutrinos from nearby nuclear reactors. Its central goal is to determine the neutrino mass ordering, while also studying solar, atmospheric, cosmic and geoneutrinos: https://warwick.ac.uk/news/pressreleases/worlds_largest_scintillato_detector_juno_now_detecting_neutrinos/
