In July 2026, group members carried out the advanced three-dimensional total scattering experiment at the SPring-8 synchrotron radiation facility in Japan for three-dimensional pair distribution function (3D-PDF) structural analysis. As one of the world’s most advanced synchrotron light sources, SPring-8 provides ultra-high-brightness and high-energy x-rays with excellent beam quality. In this experiment, high-energy X-rays were utilized to collect both Bragg diffraction and diffuse scattering signals, enabling the precise characterization of long-range ordered lattice structures and short-range local atomic arrangements of the materials.

课题组成员前往日本同步辐射设施SPring-8开展三维全散射实验

2026年7月，课题组成员前往日本SPring-8同步辐射光源开展新型三维全散射实验，用于三维原子对分布函数（3D-PDF）结构解析。SPring-8为全球知名的先进辐射光源之一，可提供高亮度及高能量X射线束。本次实验利用高能X射线同时收集布拉格衍射与漫散射信号，实现材料长程有序晶格结构与短程局域原子排布的精准解析。
