    摘要: An X-ray system includes, first and second X-ray channels (XCs), a spot sizer and a processor. The first XC is configured to: (i) direct a first X-ray beam for producing a spot on a surface of a sample, and (ii) produce a first signal responsively to a first X-ray radiation received from the surface. The spot sizer is positioned at a distance from the surface and is shaped and positioned to set the spot size by passing to the surface a portion of the first X-ray beam. The second XC is configured to: (i) direct a second X-ray beam to the surface, and (ii) produce a second signal responsively to a second X-ray radiation received from the surface, and the processor is configured to: (i) perform an analysis of the sample based on the first signal, and (ii) estimate the size of the spot based on the second signal.

    摘要: It is made possible to surely supply a porous complex crystal in which a sample is soaked, into a single-crystal X-ray structure analysis apparatus. There is provided a soaking machine for soaking a sample, comprising a supply section that supplies the sample to the porous complex crystal held by a sample holder 310, a temperature control section that controls a temperature of the porous complex crystal, a drive section that drives the supply section, and a control section that controls the supply section, the temperature control section and the drive section. The supply section supplies the sample to the porous complex crystal held by the sample holder 310 inside the applicator 311; and the temperature control section controls the temperature of the porous complex crystal held by the sample holder 310, inside the applicator 311 into which the sample is supplied.

    摘要: An evaluation device includes an X-ray diffraction measuring device configured to acquire a first X-ray locking curve having a first main peak and a first sub-peak partially overlapping the first main peak by measuring an X-ray locking curve of a first portion of a sample having a crystalline material. The evaluation device includes an analysis device configured to separate the first sub-peak from the first main peak, perform first evaluation of a crystal defects or distortion of the sample based on a peak position, peak intensity, or a half width of the separated first sub-peak, and output the first evaluation.

    摘要: The present invention provides an X-ray diffraction measurement apparatus configured to measure properties of an object to be measured M based on X-ray diffraction generated by the object to be measured at an intersection position between an incident optical axis and outgoing optical axes, the X-ray diffraction measurement apparatus including: three slits of a linear shape through which X-rays pass and that are arranged so as to be inclined in an axial direction of the outgoing optical axis; a first two-dimensional detector and a second two-dimensional detector that detect the X-rays passing through the slits within a detection region; and a profile calculator that calculates diffraction profiles indicating intensities of the passing X-rays detected by the two-dimensional detectors, for each of the passing X-rays, thereby being capable of simultaneously obtaining measurement results relating to properties of a plurality of materials having different diffraction angles.

    摘要: A method for displaying measurement results from X-ray diffraction measurement, in which a sample is irradiated with X-rays and the X-rays diffracted by the sample are detected by an X-ray detector, comprises: (1) forming a one-dimensional diffraction profile by displaying, on the basis of output data from an X-ray detector, a profile in which one orthogonal coordinate axis shows 2θ angle values and another orthogonal coordinate axis shows X-ray intensity values; (2) forming a two-dimensional diffraction pattern by linearly displaying X-ray intensity data, for each 2θ angle value and on the basis of output data from the X-ray detector; the X-ray intensity data being present in the circumferential direction of a plurality of Debye rings formed at each 2θ angle by diffracted X-rays; and (3) displaying the two-dimensional diffraction pattern and the one-dimensional diffraction profile so as to be aligned such that the 2θ angle values of both coincide with each other.
