报告简介：

 The target station converts high energy (1.6GeV,62.5µA) protons into lower-energy (< 1 eV), short-pulsed neutron beams optimized for the neutron scattering instruments. The interaction between the pulsed high-energy proton beam with the light water-cooling tungsten target produces the fast neutrons through the spallation reaction. Then the fast neutron will be moderated into short the cold, thermal and epithermal neutrons by the decoupled and poisoned hydrogen moderator, the coupled hydrogen moderator and the ambient decoupled water moderator. This compact mode makes the Chian Spallation Neutron Source(CSNS) has very high neutron efficiency and operates smoothly. CSNS has 11 instruments open to users and about 9.5% is for industry applicaitons. CSNS will upgrade to 500KW and provide other 9 instruments to users and finish its upgrades in Oct.2026. The multi-physics instrument (MPI) at CSNS is the latest built neutron total scattering diffractometer in the world which is funded by.

报告人简介： 

Prof. Wen Yin, PhD, tenured professor of University of Chinese Academy of Sciences. Director of the Neutron Science Division at the Science Center of Spallation Neutron Source. She graduated from Shanxi University in 2004, majoring in theoretical physics. She mainly focuses on neutron physics and irradiation effects research. She also focuses on developing analysis methods of neutron total scattering. She uses neutron scattering techniques, transmission electron microscopy, and density functional theory to study materials structure and performance change under irradiation. Over the years, she has published over 100 papers on Nature, Science, Science Advances, Journal of the American Chemical Society, Physics Review B et al. She also is the director of Dongguan Female Federation of Science and Technology, working on building a bridge between industry user and CSNS.
