上海同步辐射装置(SSRF)的光束线BL16B1致力于研究聚合物、纳米材料、介孔材料、胶体、液晶、金属材料等的微观结构和动力学过程。目前，终端用户可以在该光束线上进行各种实验，如SAXS、广角X射线散射(WAXS)、同时SAXS/WAXS、掠入射SAXS和反常SAXS技术。样品到探测器的距离从0.2米到5米可调，在10keV的入射X射线下，常规SAXS的Q范围是0.03-3.6 nm-1，而同时SAXS/WAXS模式可以获得0.06-33 nm-1的连续Q范围。亚秒级的时间分辨SAXS测量是在2013年通过光束线升级实现的。本文详细介绍了SAXS光束线的现状、性能和应用。
Beamline BL16B1 at Shanghai Synchrotron Radiation Facility(SSRF) is dedicated to studying the microstructure and dynamic processes of polymers, nanomaterials, mesoporous materials, colloids, liquid crystals,metal materials, etc. At present, SAXS, wide angle X-ray scattering(WAXS), simultaneous SAXS/WAXS,grazing incident SAXS, and anomalous SAXS techniques are available for end user to conduct diverse experiments at this beamline. The sample-to-detector distance is adjustable from 0.2 m to 5 m. The practicable q-range is 0.03–3.6 nm-1at incident X-ray of 10 ke V for conventional SAXS whilst a continuous q-region of0.06–33 nm-1can be achieved in simultaneous SAXS/WAXS mode. Time-resolved SAXS measurements in sub-second level was achieved by the beamline upgrating in 2013. This paper gives detailed descriptions about the status, performance and applications of the SAXS beamline.
