![]() JUNO is operated by the Institute of High Energy Physics under the Chinese Academy of Sciences (CAS). Besides neutrinos from nuclear reactors, JUNO can also study neutrinos from supernova, the sun, earth and our atmosphere.Īn aerial view of JUNO, March 23, 2021. With neutrinos going through the detector, a very small part of them will interact with the liquid scintillator, producing scintillation light detected by the photomultiplier tubes as neutrino signals for further calculation and study. Upon completion, the acrylic sphere will be filled with a liquid scintillator, and the water pool will cover the whole detector to protect it from the natural radioactivity of the surrounding rocks. The photomultiplier tubes and other parts will also be mounted to the steel grid simultaneously. The whole structure is constructed at the center of a water pool under a huge cave in Jiangmen.Ī steel elevating platform has been made in the water pool so that an acrylic sphere can be constructed inside the steel grid layer by layer from top to bottom. The main structure, a huge spherical stainless-steel grid, China's largest so far, will support the core of JUNO, a 13-story-tall spherical detector which will be covered by 20,000 light detecting photomultiplier 20-inch (50.8cm) tubes and filled with 20,000 tonnes of specially formulated liquid. ![]() CFPĬhina has achieved a major breakthrough in the building of its next-generation neutrino detector, Jiangmen Underground Neutrino Observatory (JUNO), with the completion of the detector's main structure, some 700 meters underground in Jiangmen City, south China's Guangdong Province. Groundbreaking for the LBNF excavation and construction at Sanford Lab occurred on July 21, 2017.The construction site of JUNO about 700 meters underground, February 20, 2017. The Long-Baseline Neutrino Facility will provide the neutrino beamline and the infrastructure that will support the DUNE detectors. Two prototype far detectors are at the European research center CERN. The first started taking data in September 2018 and the second is under construction. These detectors will enable scientists to search for new subatomic phenomena and potentially transform our understanding of neutrinos and their role in the universe. A second, much larger, detector will be installed more than a kilometer underground at the Sanford Underground Research Laboratory in Lead, South Dakota - 1,300 kilometers downstream of the source. One detector will record particle interactions near the source of the beam, at the Fermi National Accelerator Laboratory in Batavia, Illinois. Discoveries over the past half-century have put neutrinos, the most abundant matter particles in the universe, in the spotlight for further research into several fundamental questions about the nature of matter and the evolution of the universe - questions that DUNE will seek to answer.ĭUNE will consist of two neutrino detectors placed in the world’s most intense neutrino beam. ![]() The Deep Underground Neutrino Experiment (DUNE) is a leading-edge, international experiment for neutrino science and proton decay studies.
