在本文中,我们展示了第一种方法的空间分辨中子去极化数据的三维重建。我们将展示使用安装在慕尼黑FRM II的摄影光束线ANTARES上的3He偏振器和分析器的纵向偏振分析装置上的位置敏感CCD探测器的测量结果。用非均匀Pd1−xNix样品采集的数据的层析重建表明,这种方法是识别样品内部不同磁性区域的强大工具。
In this paper we show a first approach to the three dimensional reconstruction of spatially resolved neutron depolarization data. We will show measurements with a position sensitive CCD detector on a longitudinal polarization analysis setup using 3He polarizers and analyzers installed at the radiography beamline ANTARES at FRM II, Munich. A tomographic reconstruction of data acquired with an inhomogeneous Pd1−xNix sample shows that this method is a powerful tool to identify regions of different magnetic properties inside the sample.
