The Neutrino experiment in Jiangmen, a large scientific device, is under intense construction. The central detector located 700 meters underground has recently completed the installation of the equatorial layer of the world's largest single organic glass sphere, and the overall project of the detector is more than half. Neutrino is the most mysterious Elementary particle in the universe. Its research is of great significance for understanding the origin of the universe and is the most advanced basic research in the world. The Neutrino experiment in Jiangmen takes measuring the order of Neutrino quality as the primary scientific goal. Its core detection equipment is located in the center of the pool in the 700 meter underground experimental hall. It consists of a stainless steel reticulated shell with a diameter of 41 meters, a plexiglass ball with a diameter of 35.4 meters, 20000 tons of liquid scintillators, 45000 Photomultiplier tube and other key components. This world's largest single organic glass ball is made up of 263 huge spherical panels installed and spliced layer by layer from top to bottom on site. The equatorial layer is the layer with the largest horizontal diameter, consisting of 15 3-ton spherical panels spliced together. Each panel is about 8 meters long, 3 meters wide, and only 120 millimeters thick. It is expected that the Jiangmen Neutrino experiment will complete the installation of the core structure of the detector by the end of this year, and the operation of data acquisition will begin by the end of next year. It is expected to produce a series of major achievements in the accurate measurement of the Neutrino mass sequence and in the research of supernovae, Earth and solar Neutrino. (New News Agency)
