摘要
本文报告了在实际仪器中首次观测到的准直戈贝尔反射镜的准布拉格散射。根据所获得的实验数据和所做的数值分析,得出结论认为,在建造用于 X 射线衍射仪和光谱仪的带多层反射镜的真实设备时,有必要考虑准布拉格散射的影响,特别是在使用位置敏感探测器进行小角散射时。
Observation of quasi-Bragg scattering by Goebel mirrors
This paper reports the first observation of quasi-Bragg scattering from collimating Goebel mirrors in a real instrument. On the basis of the experimental data obtained and the numerical analysis performed, it is concluded that it is necessary to take into account the effect of quasi-Bragg scattering when constructing real devices with multilayer mirrors for use in X-ray diffractometry and in spectroscopy, especially for small-angle scattering with position-sensitive detectors.
期刊介绍:
Many research topics in condensed matter research, materials science and the life sciences make use of crystallographic methods to study crystalline and non-crystalline matter with neutrons, X-rays and electrons. Articles published in the Journal of Applied Crystallography focus on these methods and their use in identifying structural and diffusion-controlled phase transformations, structure-property relationships, structural changes of defects, interfaces and surfaces, etc. Developments of instrumentation and crystallographic apparatus, theory and interpretation, numerical analysis and other related subjects are also covered. The journal is the primary place where crystallographic computer program information is published.
