China News Service, Dongguan, July 29 (Li Yingmin and Li Huo) The reporter learned from the Management Committee of Songshan Lake High-tech Zone in Dongguan, Guangdong on the 29th that the large scientific installation in the Songshan Lake Science City, China’s Spallation Neutron Source, is the first cooperative spectrometer— —The multi-physical spectrometer has recently passed the acceptance check and will be opened for operation in October this year.
It is understood that the spectrometer is a scientific research project jointly developed by China's Spallation Neutron Source and Guangdong and Hong Kong. It will play an important role in China's materials science, condensed matter physics, life science, nanometer and other disciplines. It will also serve the Guangdong-Hong Kong-Macao Greater Bay Area. The development of scientific and technological innovation and the Guangdong-Hong Kong-Macao Neutron Scattering Science and Technology Joint Laboratory provide an important research platform support.
"China's spallation neutron source multi-physical spectrometer construction, one of the main goals is to carry out long-range ordered but locally disordered materials structure research." Deputy Director of the Department of Neutron Science, Dongguan Research Department, Institute of High Energy Physics, Chinese Academy of Sciences, China Yin Wen, head of the Spallation Neutron Source Multi-Physical Spectrometer, said that, for example, the power battery that the public is more familiar with is this type of substance, and the neutron multi-physics spectrometer will be used for research.
It is understood that the design flux of the multi-physical spectrometer is 4 to 5 times that of the British spallation neutron source ISIS total scattering spectrometer GEM with the same power, and the resolution is comparable to the megawatt-level American spallation neutron source SNS total scattering spectrometer. NOMAD is equivalent.
Chen Yanwei, director of the Spallation Neutron Source Science Center and deputy director of the Institute of High Energy Physics of the Chinese Academy of Sciences, said that China's spallation neutron originated from its official operation on August 23, 2018, and attracted people from related fields in the Greater Bay Area and the world. A large number of scientific and technological workers came to participate in the research, and the siphon effect of large scientific devices continued to appear, effectively supporting the technological innovation and development of the Greater Bay Area.
