<P>PROBLEM TO BE SOLVED: To provide an X-ray spectroscopic system capable of easily selecting and extracting multi-wavelength X-rays with wavelength in a prescribed wavelength range from white X-rays with continuous wavelength. <P>SOLUTION: An X-ray spectroscopic system comprises an X-ray wave guide that white X-rays enter, and X-ray selection means that separates diffracted X-rays, with different diffraction angles, which leave the X-ray wave guide, and that selects and extracts multi-wavelength X-rays in a prescribed wavelength range from the diffracted X-rays. The X-ray wave guide has a core and a clad. The core is formed of a periodic structure in which a basic structure including a plurality of substances having different real parts of refractive indexes shows periodicity. The total reflection critical angle of the X-rays at the interface between the clad and the core is greater than Bragg angles due to the periodicity of the basic structure of the periodic structure of the core. <P>COPYRIGHT: (C)2013,JPO&INPIT |
