填补空白！我国首台，交付使用

Core Points - The first high-energy direct geometry inelastic neutron scattering time-of-flight spectrometer in China has been accepted and put into use, marking a significant advancement in material dynamics research [1][3] - This spectrometer will provide experimental conditions for research in physics, chemistry, materials science, mechanics, and interdisciplinary studies [1] Group 1 - The unique feature of the spectrometer is its ability to utilize the non-charged and penetrating nature of neutrons to directly probe the microscopic movements within materials [3] - It fills the gap in inelastic neutron scattering above 100 meV in China, allowing for the measurement of both spatial distribution and energy changes of scattered neutrons [3] - The spectrometer can measure the dynamic behavior of microscopic structures in both momentum and energy space, enhancing the understanding of material properties [3] Group 2 - The spectrometer employs a combination of Fermi chopper and bandwidth chopper to enable rapid switching between multi-wavelength and single-wavelength modes [3]
