Patent ID: 7209541

Claim:
An X-ray analysis apparatus in which X-rays emitted from an X-ray source are applied to a sample and semiconductor X-ray detecting means detects the X-rays diffracted by the sample, said X-ray analysis apparatus comprising: scan-moving means for scan-moving the semiconductor X-ray detecting means in a plane that is arranged behind the sample by a predetermined distance and on which X-rays, diffracted and diverging from the sample, form an X-ray diffraction image the semiconductor X-ray detecting means having an X-ray receiving surface defined by a plurality of pixels arranged in rows and columns, the X-ray receiving surface being smaller than the plane; and charge-transfer signal generating means for generating a charge-transfer signal in the semiconductor X-ray detecting means, every time the semiconductor X-ray detecting means is moved a distance corresponding to a width of one pixel; wherein motion of the semiconductor X-ray detecting means and the generation of the charge-transfer signal are synchronized with each other to achieve a time delay integration; and the scan-moving means causes the semiconductor X-ray detecting means to move back and forth linearly along a plurality of scanning lines which extend respectively along a horizontal direction and are arranged in parallel to each other along a vertical direction within the plane.
