China's JUNO Neutrino Detector Achieves World-Leading Precision in Solar Neutrino Research
November 24, 2025
Experts view JUNO as a world‑leading facility central to neutrino oscillation research for the coming years, potentially driving new techniques and benefiting broader science and industry.
JUNO unites more than 700 researchers from over 17 countries, reflecting its international scope and strong collaboration with European research organizations.
JUNO represents China’s broader push to become a science and technology powerhouse, backed by substantial basic research funding, and it complements global projects like DUNE and Hyper‑Kamiokande.
Data are collected from neutrinos produced by two nearby nuclear power plants, Yangjiang and Taishan, 53 kilometers away, with the site shielded by a granite mountain to minimize cosmic interference.
JUNO sits within a global, multi‑nation neutrino research ecosystem that includes the US DUNE and Japan’s Hyper‑Kamiokande, with JUNO currently leading in a specific area of neutrino oscillation measurements.
While JUNO and its peers pursue overlapping aims, their efforts are largely complementary, collectively advancing the world’s understanding of neutrinos.
JUNO is one of several large‑scale neutrino experiments under development, and its science questions are designed to complement those of DUNE and Hyper‑Kamiokande to push the field forward.
Experts describe JUNO as world‑leading and highlight China’s readiness to invest heavily in basic research to tackle technology chokepoints and sustain a long‑term, multi‑decade physics program.
Early data show higher‑precision measurements of solar neutrino oscillation parameters, confirming JUNO’s performance as designed within a short window after operation began.
China reports first results from JUNO, a next‑generation neutrino detector buried about 700 meters underground in Guangdong, built to study neutrinos with exceptional precision.
JUNO encompasses a 20,000‑tonne liquid scintillator in a giant acrylic sphere surrounded by more than 40,000 light detectors, with two nearby reactors 53 kilometers away serving as the neutrino source.
