JIANGMEN, Nov. 19 (Xinhua) -- The world's largest transparent spherical neutrino detector in south China's Guangdong Province reported its first achievement on Wednesday, marking a major step of its decade-long construction.
Using 59 days of effective data after the start of operation on Aug. 26 this year, Jiangmen Underground Neutrino Observatory (JUNO) has already measured two of the solar neutrino oscillation parameters with a factor of 1.5 to 1.8 better precision than previous experiments.
