After more than nine years of dedicated construction, China's Jiangmen Underground Neutrino Observatory (JUNO) has successfully completed its main structure on Wednesday. Situated in Jiangmen City, Guangdong Province, the observatory is set to begin operations next year.
JUNO boasts the world's largest transparent spherical detector, positioned 700 meters underground to capture elusive neutrinos—often referred to as \"ghost particles.\" These particles hold the key to unraveling some of the universe's deepest mysteries.
The observatory features a 44-meter-deep tank encased in a stainless steel mesh shell with a diameter of 41 meters, housing a 35.4-meter organic glass ball. Equipped with 45,000 photomultiplier tubes, JUNO is meticulously designed to detect the faint interactions between neutrinos and the liquid scintillator inside. This groundbreaking facility aims to determine the neutrino mass hierarchy, advancing our understanding of both the infinitesimally small and the infinitely vast aspects of the cosmos.
