The newly built MagSAXS (magnetic small-angle X-ray scattering) set-up dedicated to the direct two-dimensional measurement of magnetic scattering using polarized synchrotron radiation in extreme sample environments is presented. Pure optical transport of the image is used to record the magnetic scattering with a two-dimensional CCD visible-light camera. The set-up is able to probe magnetic correlation lengths from the micrometer down to the nanometer scale. A detailed layout is presented along with preliminary results obtained at several beamlines at Synchrotron SOLEIL. The presented examples underline the wide range of possible applications spanning from correlation lengths determination to Fourier transform holography.
介绍了一种新建成的 MagSAXS(磁小角 X 射线散射)装置,该装置专门用于在极端样品环境中使用偏振同步辐射进行磁散射的直接二维测量。采用纯光学传输来记录二维 CCD 可见光相机的磁散射。该装置能够探测从微米到纳米尺度的磁相关长度。本文详细介绍了该装置的结构,并给出了在 Synchrotron SOLEIL 的几个光束线上获得的初步结果。所给出的示例强调了可能的应用范围广泛,从相关长度的确定到傅里叶变换全息术。
