Microbeam-forming methods for synchrotron radiation
TLDR
The increasing availability of synchrotron x-ray sources has stimulated the development of advanced hard X-ray (E⩾5 keV) microprobes.Abstract:
The increasing availability of synchrotron x-ray sources has stimulated the development of advanced hard x-ray (E⩾5 keV) microprobes. It is now possible to achieve intense submicron x-ray beams with a variety of techniques including Fresnel zone plates, Kirkpatrick–Baez mirrors, tapered capillaries and Bragg–Fresnel optics. These synchrotron-based x-ray microprobes can be used for ultra-sensitive elemental detection by x-ray fluorescence/absorption and for microdiffraction to identify phase and strain with submicron resolution. Advanced methods for forming microbeams are reviewed and the relative merits of each approach are discussed. The efficient techniques developed for synchrotron beams can also be used to tailor the beam properties from conventional x-ray sources. © 1997 This article is a US Government work and, as such, is in the public domain in the United States of Americaread more

Pressure-induced amorphization and polyamorphism: Inorganic and biochemical systems
TL;DR: Pressure-induced amorphization (PIA) is a phenomenon that involves an abrupt transition between a crystalline material and an amorphous solid through application of pressure at temperatures well below the melting point or glass transition range.

White microbeam diffraction from distorted crystals
TL;DR: In this article, a general description of white-beam scattering from grains with dislocations is presented, applied to examples with equal numbers of positive and negative Burger vectors (paired and unpaired) and with unpaired dislocation of one sign (geometrically necessary).

X-Ray Fluorescence Microprobe for Chemical Analysis
TL;DR: The analytical application of synchrotron radiation is the subject of this chapter and must offer some important advances over present analytical techniques or little justification can be found for the use of a facility remote to most users.
