【摘要】：Offering high-brilliance X-ray beams on micrometer length scales,the μSAXS at SSRF BL16 B1 has been established with a KB mirror system for studying small sample volumes,or probing microscopic morphologies.The SAXS minimum q value is 0.1 nm~(-1) with a flux of 1.5×10~(10) photons/s.Two position-resolved scanning experimental methods,STXM and CT,are combined with μSAXS.To improve the significant smearing effect in the horizontal direction,an effective and easy-to-use desmearing procedure for two-dimensional SAXS patterns based on blind deconvolution was developed,and the deblurring results demonstrate the good restoration effect for the defocused image.Finally,a bamboo sample was used in the SAXS-CT experiment to illustrate the performance of the μSAXS method.
