Abstract

Various X-ray techniques are employed to investigate specimens in diverse fields. Generally, scattering and absorption/emission processes occur due to the interaction of X-rays with matter. The output signals from these processes contain structural information and the electronic structure of specimens, respectively. The combination of complementary X-ray techniques improves the understanding of complex systems holistically. In this context, we introduce a multiplex imaging instrument that can collect small-/wide-angle X-ray diffraction and X-ray emission spectra simultaneously to investigate morphological information with nanoscale resolution, crystal arrangement at the atomic scale and the electronic structure of specimens.

摘要

各种X射线技术被用于研究不同领域的标本。一般来说，由于X射线与物质的相互作用，会发生散射和吸收/发射过程。这些过程的输出信号分别包含标本的结构信息和电子结构。互补X射线技术的结合有助于从整体上更好地理解复杂系统。在此背景下，我们介绍一种多重成像仪器，它可以同时收集小角/广角X射线衍射和X射线发射光谱，以研究具有纳米级分辨率的形态信息、原子尺度的晶体排列以及标本的电子结构。
