China Turns On Giant Neutrino Detector That Took a Decade To Build


China has turned on the world's most sensitive neutrino detector after more than a decade of construction. The Register reports: The Jiangmen Underground Neutrino Experiment (JUNO) is buried 700 meters under a mountain and features a 20,000-tonne "liquid scintillator detector" that China's Academy ...

The Register reports: The Jiangmen Underground Neutrino Experiment (JUNO) is buried 700 meters under a mountain and features a 20,000-tonne "liquid scintillator detector" that China's Academy of Science says is "housed at the center of a 44-meter-deep water pool." The Chinese Academy of Science's Journal of High Energy Physics says trials of JUNO succeeded, suggesting it will be able to help scientists understand why some neutrinos are heavier than others so we can begin to classify the different types of the particle -- a key goal for the facility. The Journal also reports that scientists from Japan, the United States, Europe, India, and South Korea, are either already using JUNO or plan experiments at the facility.
