摘要
小角Ｘ射线散射（ＳＡＸＳ）实验站配置有ＳＡＸＳ相机、在线控制及数据获取系统．ＳＡＸＳ相机由位置精度为１μｍ的狭缝系统、用以监测光强的电离室、在垂直于束流的平面内能作水平和垂直两个方向遥控调节的样品台和可调长度低真空管道等部分组成，真空管道的两端有２５μｍ厚的Ｋａｐｔｏｎ膜密封，探测器为闪烁计数器．该装置的角分辨优于０．６ｍｒａｄ．
The small angle x-ray scattering (SAXS) station is located at 34m from the source in the downstream of the x-ray diffraction station. The station is equipped with a SAXS camera, a detector, an alignment carriage and on-line data acquisition and control system. The SAXS camera consists of a slit-system with position precision 1μm, a remotely controlled sample holder with vertical and horizontal translations at the plane normal to photon beam and a vacuum pipe with 0.13Pa. The research for this station is directed on the static and dynamic structure, phase composition and phase transmission in various fields such as molecular biology, materialscience, polymer chemistry and metallurgy.
