Abstract:
1. An X-ray intensity correction method for correcting an intensity of diffracted X-rays by making a background uniform, the method comprising: focusing X-rays on a sample for correction placed at a gonio center to produce fluorescent X-rays, entering the fluorescent X-rays excited by the X-rays into a raster element being formed by polycapillaries and having a unique focal point, and detecting the fluorescent X-rays having passed through the raster element; and adjusting an arrangement of the raster element so that the fluorescent X-rays can uniformly be detected regardless of a detecting position, wherein the arrangement of the raster element is adjusted to a position determined based on a comparison between a minimum value and a maximum value of an intensity of a two-dimensional image obtained by the fluorescent X-rays.
