X-Ray Point Focusing Using Cylindrically Bent Crystals with Modulated Structures for Synchrotron X-Ray Beams

摘要

Micron or submicron spatial resolution for x-ray microfluorescence analysis has been pursued using various x-ray point focusing methods, ~(1-4)such as transmission zone plates, tapered capillaries, and Bragg Fresnel lenses. Point focusing using bent crystals does not seem to be a desirable means for achieving a microbeam size, although it is a traditional technique which utilizes perfectly curved crystal surfaces to focus x rays emanating from the source.
