GUANGZHOU, Aug. 26 (Xinhua) — A neutrino detector called the Jiangmen Underground Neutrino Observatory (JUNO) was officially put into operation in Jiangmen, south China's Guangdong Province, on Tuesday.
“This facility has become the world’s first dedicated, ultra-large-scale, high-precision system for megascience neutrino research,” said Wang Yifang, an academician of the Chinese Academy of Sciences and the chief scientist of the JUNO program. “The facility will help us get answers to the main questions concerning the materials and properties of the Universe.”
JUNO, which took more than 10 years to build, is designed to sort neutrinos by weight and measure their oscillation characteristics. The facility will also be used to study supernovae and terrestrial and solar neutrinos.
The key element of JUNO is a sphere of organic glass containing 20,000 tons of liquid scintillator. When neutrinos pass through this special liquid, it begins to glow. At this time, the flashes of light are detected by photomultipliers, which analyze the characteristics of the almost elusive particles.
JUNO was developed by the Institute of High Energy Physics of the Canton of Sciences in collaboration with 700 scientists from 17 countries and regions of the world. -0-
