On April 26, the Institute of High Energy Physics of the Chinese Academy of Sciences (Institute of High Energy Physics, Chinese Academy of Sciences) announced to the media that in Jiangmen City, Guangdong Province, at a depth of 700 meters under Dashi Mountain, the second large-scale neutrino experimental project hosted by China—— The Jiangmen Neutrino Experiment is in full swing.

  The Jiangmen Neutrino Experiment is a large scientific device with the primary scientific goal of measuring the order of neutrino masses. After its completion, it will cooperate with Japan's "Top Kamioka Neutrino Detector" and the United States' "Deep Underground Neutrino Experiment" facility Formed the leading trend of neutrino research.

  The video provided by the High Energy Institute of the Chinese Academy of Sciences shows that recently, in the Jiangmen Neutrino Experiment Underground Experiment Hall under construction, in a 44-meter-deep pool, the installation project of the core equipment of the experiment, a detector with a diameter of 41 meters, is being carried out in an orderly manner. .
