(241011) -- JIANGMEN, 11 ottobre 2024 (Xinhua) -- Wang Yifang (L), capo scienziato dell'Osservatorio dei neutrini sotterranei di Jiangmen (JUNO) e capo dell'Istituto di fisica ad alta energia (IHEP) del CAS, parla con il suo collega in una sala degli esperimenti a Jiangmen, nella provincia del Guangdong della Cina meridionale, 10 ottobre 2024. La Cina ha costruito il rivelatore sferico trasparente più grande del mondo a 700 metri sottoterra per catturare neutrini sfuggenti, spesso soprannominati "particelle fantasma", per svelare i segreti di infinitesimamente piccoli e infinitamente vasti dell'universo.

(241011) -- JIANGMEN, Oct. 11, 2024 (Xinhua) -- Wang Yifang (L), chief scientist of the Jiangmen Underground Neutrino Observatory (JUNO) and head of the Institute of High Energy Physics (IHEP) of the CAS, talks with his colleague at an experiment hall in Jiangmen, south China's Guangdong Province, Oct. 10, 2024. China has constructed the world's largest transparent spherical detector 700 meters underground to capture elusive neutrinos, often dubbed "ghost particles, " to unravel the secrets of the infinitesimally small and the infinitely vast in the universe. The 12-story-tall acrylic sphere with a diameter of 35.4 meters, buried deep in a granite layer of a hill in Kaiping, Jiangmen City in south China's Guangdong Province, is the core part of JUNO, a gigantic and complex scientific facility. The construction of the challenging project, launched by the Chinese Academy of Sciences (CAS) and the Guangdong government in 2015, has entered the final stage. Installation of the entire device is expected to be completed by the end of November, and the full operation of the facility is scheduled for August 2025, according to the Institute of High Energy Physics (IHEP) of the CAS, the project's leading institution. The observatory is designed to help scientists better understand the neutrino mass hierarchy by detecting reactor neutrinos from the nearby Yangjiang and Taishan nuclear power plants with an unprecedented 3 percent energy resolution, said Wang Yifang, chief scientist of JUNO and head of the IHEP. The facility will also help scientists conduct other cutting-edge studies such as observing supernova, atmospheric and solar neutrinos. (Xinhua/Jin Liwang)
