我国研发的微观世界“超级相机”交付使用

Core Viewpoint - The first high-energy direct geometry inelastic neutron scattering time-of-flight spectrometer in China has been accepted and put into use, serving as a significant research platform for material dynamics properties across various scientific fields [1][2]. Group 1: Instrument Capabilities - The high-energy inelastic spectrometer functions like a "super camera," capable of observing not only the static structure of materials but also the dynamic processes of atoms and molecules on a picosecond timescale [1]. - It utilizes the unique properties of neutrons, which are uncharged and have strong penetration capabilities, to directly detect microscopic movements within materials [1]. - The 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]. Group 2: Research Applications - The instrument is equipped with a white beam Laue camera mode, facilitating rapid detection of structural and magnetic information in single crystal materials [2]. - It will provide critical microscopic structural dynamics information for cutting-edge research in high-temperature superconductivity, quantum magnetic effects, thermoelectric material transport properties, ion diffusion mechanisms in batteries, and the activity of biological materials [2].
