The collaboration was formed in July 2014 and construction began January 10, 2015. [10], "JUNO" redirects here. The much larger distance to the reactors (compared to less than 2 km for the Daya Bay far detector) makes the experiment better able to distinguish neutrino oscillations, but requires a much larger, and better-shielded, detector to detect a sufficient number of reactor neutrinos. In the near future, the mystery of the mass order of neutrinos will be revealed, and the precise measurement of neutrino oscillation parameters, celestial neutrinos, and earth neutrino Internationally leading scientific achievements have been made in the search for new physics and physics. Such a finding corroborates an earlier anomaly seen at the Liquid Scintillator Neutrino Detector (LSND), an experiment at Los Alamos National Laboratory in New Mexico. New neutrino detection experiment in China up and running. The Daya Bay experiment also accurately measured the energy spectrum of the reactor neutrino, and found that compared with the theoretical model, there are two obvious anomalies that require further research in the future.
