Abstract: Small-sized X-ray CT apparatus obtaining a cross-section or 3D image of a sample, using X-rays. Included: an X-ray generating apparatus irradiating X-rays on the sample; an X-ray detecting device detecting X-rays passing through the sample; and a device processing a detection signal from the X-ray detecting device, to re-structure the cross-section or 3D image of the sample; an X-ray shielding member having an opening portion for introducing the sample therein on one end surface and being treated with an X-ray protection process on an entire periphery thereof; and a means rotationally driving the X-ray shielding member, wherein the X-ray generating apparatus and the X-ray detecting device are treated with the X-ray protection process, respectively, and are fixed on a wall surface of the X-ray shielding member at positions opposing to each other, putting an rotation axis thereof therebetween, and thereby constructed with the X-ray shielding member in one body.

Abstract: An X-ray analysis apparatus having a function for enabling a plurality of measurement methods to be implemented, the apparatus having: measurement software for implementing each of the individual measurement methods and acquiring measurement data; analysis software for performing a predetermined analysis on the measurement data and acquiring analysis data; reduced-size-image-creating means for creating a reduced-size image on the basis of each item of the measurement data and the analysis data; analysis-icon-creating means for creating an icon for denoting the analysis software; and image display means for displaying the reduced-size image and the icon on the same screen while indicating that the reduced-size image and the icon are correlated.

Abstract: An X-ray analysis apparatus having a function for enabling a plurality of measurement methods to be implemented, the X-ray analysis apparatus having: a measurement system capable of implementing a plurality of measurement methods; measurement software for implementing, in a selective manner, each of the measurement methods; a material evaluation table for storing information relating to a material that may be measured, and a name of an evaluation performed on the material; an input device for inputting the information relating to the material; a wizard program for performing computation for selecting the name of an evaluation on the basis of the information relating to the material inputted using the input device; and a wizard program for selecting a corresponding measurement method on the basis of the selected name of the evaluation.

Abstract: An X-ray intensity correction method makes the background uniform by adjusting a raster element and an X-ray diffractometer. An X-ray intensity correction method for correcting the intensity of diffracted X-rays includes the steps of focusing X-rays on a sample for correction placed at a gonio center, entering fluorescent X-rays excited by the focused X-rays into a raster element formed by polycapillaries and having a unique focal point, detecting the fluorescent X-rays having passed through the raster element; and adjusting the arrangement of the raster element so that the fluorescent X-rays can uniformly be detected regardless of the detecting position. Since fluorescent X-rays are used, it is possible to adjust the position of the raster element because if the focal point of the raster element coincides with the gonio center, the intensity becomes uniform regardless of the detected position.
