Scientists switch on the world’s largest neutrino detector deep underground that took over a decade to build
Deep beneath southern China, JUNO has launched one of the most ambitious neutrino experiments in history. With its massive 20,000-ton liquid scintillator detector now operational, it’s poised to answer one of particle physics’ greatest mysteries: the true ordering of neutrino masses. Built over more than a decade and involving hundreds of scientists worldwide, JUNO not only promises to resolve questions about the building blocks of matter but also to open entirely new frontiers—from exploring signals of supernovae to hunting for evidence of exotic physics.
Built over more than a decade and involving hundreds of scientists worldwide, JUNO not only promises to resolve questions about the building blocks of matter but also to open entirely new frontiers—from exploring signals of supernovae to hunting for evidence of exotic physics. Located 700 meters underground near Jiangmen city in the Guangdong Province, JUNO detects antineutrinos produced 53 kilometers away by the Taishan and Yangjiang nuclear power plants and measures their energy spectrum with record precision. The worldwide liquid scintillator community has pushed the technology to its ultimate frontier, opening the path towards the ambitious physics goals of the experiment," commented Prof. Gioacchino Ranucci, Deputy spokesperson of JUNO and a Professor at the University of Milano and INFN-Milano.
