Depth Resolution: Sampling depth between ~20 Å to ~30 µm, depending on material properties and X-ray incidence angle Imaging/Mapping: None Lateral Resolution/Probe Size: Point focus: 0.1 mm to 0.5 mm; Line focus 2 mm to 12 mm; Microdiffraction to ~20 µm ...
In X-Ray Diffraction (XRD), these are atomic planes in crystals, which can be used to identify the material, determine the atomic structure, or measure strain. In X-Ray Reflectivity (XRR) and small angle x-ray scattering, these distances measure the dimensions of thin films and nanoscale ...

(SAD) X-ray diffraction data collected near the potassium absorption edge to show experimentally that all ion binding sites within the selectivity filter are fully occupied by K+ions. These data support the hypothesis that potassium ion transport occurs by direct Coulomb knock-on, and provide an ...
http://.msg.ku.edu/~xraylab/notes/xray.html To obtain the best results, the X-ray beam used in the diffraction experiment should all be of a single wavelength and they should be as parallel as possible. To accomplish this in practice, we use ...

Particle Scattering, X-Ray Diffraction, and Microstructure of Solids and Liquids (Lecture Notes in Physics) By Manfred L. Ristig (Editor), Klaus A. Gernoth (Editor) * Publisher: Springer * Number Of Pages: 196 * Publication Date: 2003-04-28 * Sales Rank: 5228573 * ISBN / ASIN: 35404...
This chapter addresses fundamental concepts of X-ray optics and X-ray coherence, in view of the increasing number of X-ray applications requiring nano-focused X-ray beams. The chapter is meant as a tutorial to facilitate the understanding of later chapters of this book. After the introduction ...
One of the most popular X-ray-based techniques is X-ray diffraction. A typical X-ray diffraction setup – shown in Fig. 40 –is composed of an X-ray source (either a tube, a rotating anode, a synchrotron source, or a free electron laser), primary optics (pinhole, monochromator, gratin...
