Core Insights - The first high-energy direct geometry inelastic neutron scattering time-of-flight spectrometer in China has been accepted and put into use, serving as an important platform for studying the dynamic properties of materials [1][2] - This spectrometer can observe not only the static structure of materials but also the dynamic processes of atoms and molecules on a picosecond timescale, capturing every moment of atomic and molecular vibrations, rotations, and energy transfer [1] - The unique feature of this spectrometer is its ability to directly probe the microscopic movements within materials using neutrons, which are uncharged and have strong penetration capabilities [1] Group 1 - The high-energy inelastic neutron scattering spectrometer fills a gap in China's capability for inelastic neutron scattering above 100 meV, allowing for the measurement of both spatial distribution and energy changes of scattered neutrons [1] - It can measure the dynamic behavior of microscopic structures in both momentum and energy space, utilizing a combination of Fermi chopper and bandwidth chopper for rapid switching between multi-wavelength and single-wavelength modes [1][2] Group 2 - The spectrometer features a white beam Laue camera mode, which aids in the rapid detection of structural and magnetic information of single crystal materials [2] - It will provide critical microscopic structural dynamics information for advanced research in high-temperature superconductivity, quantum magnetism, thermoelectric material transport properties, ion diffusion mechanisms in batteries, and biological material activity [2] - The collaboration project for the neutron spectrometer began in 2017 between Sun Yat-sen University and the Institute of High Energy Physics of the Chinese Academy of Sciences, culminating in the official unveiling of the spectrometer in November 2023 after over two years of debugging [2]
