成功地进行了Al K吸收边的二维反常小角X射线散射（ASAXS）测量。使用CCD检测器检测吸收限以下的对比度变化。ASAXS强度的变化的边缘附近的氧化铝纳米粉末和Guinier-Preston区的Al-Zn合金被解释的Al的反常色散。目前的结果表明，二维SAXS测量的动态范围扩展到显示Porod的法律已经实现了约1.5 keV的光子能量与使用的CCD探测器与P43荧光板光耦合。
Two-dimensional anomalous small-angle X-ray scattering (ASAXS) measurements at the K absorption edge of Al have been successfully performed. Contrast change below the absorption edge was detected with the use of a CCD detector. The change of ASAXS intensities near the edge for alumina nanopowder and that for Guinier–Preston zones in an Al–Zn alloy were explained by the anomalous dispersion of Al. The present results showed that two-dimensional SAXS measurements with a dynamic range extended to show Porod's law have been achieved for photon energies of about 1.5 keV with the use of a CCD detector optically coupled with a P43 phosphor plate.
