The advent of synchrotron radiation and the recent development of x-ray optics have rendered possible the realization of x-ray fluorescence microprobes. Various arrangements allow one to obtain micrometer-size hard x-ray beams with sufficient flux to undertake elemental mapping of trace elements. As

β¦ Synopsis
Synchrotron x-ray microbeams with less than a few lm spatial resolution have been applied to x-ray spectroscopic and di β raction studies. Among various x-ray spectrometric applications, the relatively new techniques of nearsurface x-ray Γuorescence analysis and the micro x-ray absorption Γne structure (micro-XAFS) method have been developed. For a near-surface analysis, the grazing-exit condition is used to enhance the surface sensitivity in addition to the lateral spatial resolution. With the micro-XAFS technique, chemical-state analysis over small regions and chemical-state imaging become possible. A micro x-ray spectrometric analysis with high spatial resolution was e β ectively utilized for materials characterization.
