经过多年的进化发展，首先是在布鲁克海文国家实验室的国家同步加速器光源，然后是在阿贡国家实验室的先进光子源（APS）， APS超小角度x射线散射（USAXS）设施已经被几个新的发展所改变。这些包括转换到高阶晶体光学和高x射线能量作为标准操作模式，快速飞行扫描测量也作为标准操作模式，在中间散射矢量上自动连续针孔小角x射线散射（SAXS）测量，以及相关的x射线衍射快速广角x射线散射（WAXS）测量，而不干扰样品的几何形状。每种模式都使用USAXS入射光束光学上游样品，USAXS/SAXS/WAXS测量现在可以在5分钟内完成，允许在各种样品条件下具有极大灵活性的原位和操作测量能力。本文描述了这些发展，并举例说明了它们在研究具有重要技术意义的材料现象方面的应用。综述了基于USAXS的x射线光子相关光谱和USAXS成像这两种USAXS新应用的进展。
Following many years of evolutionary development, first at the National Synchrotron Light Source, Brookhaven National Laboratory, and then at the Advanced Photon Source (APS), Argonne National Laboratory, the APS ultra-small-angle X-ray scattering (USAXS) facility has been transformed by several new developments. These comprise a conversion to higher-order crystal optics and higher X-ray energies as the standard operating mode, rapid fly scan measurements also as a standard operational mode, automated contiguous pinhole small-angle X-ray scattering (SAXS) measurements at intermediate scattering vectors, and associated rapid wide-angle X-ray scattering (WAXS) measurements for X-ray diffraction without disturbing the sample geometry. With each mode using the USAXS incident beam optics upstream of the sample, USAXS/SAXS/WAXS measurements can now be made within 5 min, allowing in situ and operando measurement capabilities with great flexibility under a wide range of sample conditions. These developments are described, together with examples of their application to investigate materials phenomena of technological importance. Developments of two novel USAXS applications, USAXS-based X-ray photon correlation spectroscopy and USAXS imaging, are also briefly reviewed.
