“…The physical and chemical properties of materials depend mainly on the elements, composition ratios, and spatial distribution in samples. The scanning X-ray fluorescence microscope is a powerful tool for fine elemental mapping, and many biomedical [1], material [2], plant [3], fossil [4], art [5], and industrial samples [6] have been observed. However, to use scanning X-ray fluorescence microscopes, highly brilliant X-rays such as synchrotron radiation (SR) at third-generation synchrotron facilities is required, and a long measurement period is required to perform fine observations at small synchrotron facilities such as the SAGA Light Source in Tosu, Japan.…”

A scanning X-ray fluorescence microscope that uses a Kirkpatrick-Baez (KB) mirror and white synchrotron radiation (SR) was developed for obtaining detailed elemental maps within a micro-meter order. The KB mirror is a total reflection mirror, and the white X-rays are focused at a focus point without chromatic aberration. Therefore, the proposed microscope can use strong white and/or pink SR and enable elemental mapping within a practical measurement time at small synchrotron facilities. A feasibility study on the developed microscope was performed by using white SR at the SAGA Light Source in Tosu, Japan. By using the developed microscope, an X-ray microbeam 1 μm in diameter was successfully formed, and a fine elemental map of a Cu mesh and a seed of eustoma were obtained.
