A laboratory X-ray microbeam for combined X-ray diffraction and fluorescence measurements

Abstract

A prototype instrument has been developed which allows the simultaneous acquisition of both X-ray diffraction and X-ray fluorescence data at a microscopic length scale for mapping studies on materials. The instrument takes full advantage of the performance of recently developed optics and detectors to optimize the detection of low-intensity signals with a monochromatic X-ray microbeam of 20 µm diameter with a laboratory X-ray source.
