Abstract: When an X-ray focused by using an X-ray lens is irradiated to a sample, there is generated an X-ray halo component at the peripheral part of the focal point of the focused X-ray in the sample and, by this, precision of an analysis of a microscopic region becomes an issue. In order to control the shape of the X-rays from the X-ray lens, a collimator is installed between the X-ray lens and the sample, with an opening part having a tapering shape in which the opening at the side toward the sample is made smaller than that at the side toward the X-ray lens.

Abstract: To provide a fluorescent X-ray analysis apparatus using a polarization for effectively measuring a minute portion of a sample surface without a necessary to prepare many kinds of secondary targets. A fluorescent X-ray analysis apparatus according to the present invention includes an X-ray tube for generating an X-ray; a sample support portion for supporting a sample receiving the X-ray; a polarization filter for receiving an X-ray to be generated from the sample receiving the X-ray; and a detector for detecting the X-ray from the polarization filter. Then, the X-ray tube, the sample, the polarization filter, and the detector are arranged so that three light paths, namely, a light path from the X-ray tube to the sample, a light path from the sample to the polarization filter, and a light path from the polarization filter to the detector intersect with each other at 90 degrees.

Abstract: A superconducting X-ray analyzer has an excitation source for irradiating an excitation beam on a surface of a sample. A detector detects X-rays reflected from the surface of the sample irradiated with the excitation beam from the excitation source. Lenses are arranged between the sample and the detector for condensing the X-rays reflected from the surface of the sample on the detector. A refrigerator having a low temperature unit is completely enclosed within a vacuum vessel for cooling the detector.
