- Fluorescent X-rays are specific X-rays emitted by elements contained in the measurement object, and give information on the chemical composition of the measurement object.
- the invention of this application is not related to fluorescent X-rays that are sensitive to the chemical composition of the sample, have specific energy, and are emitted isotropically in all directions, and are generated by a completely different principle and mechanism from fluorescent X-rays.
- the X-ray diffraction microscope apparatus of the invention of this application is an X-ray diffraction microscope apparatus that measures and images diffracted X-rays generated at a specific position on a sample when the sample is irradiated with incident X-rays.
- the X-ray diffraction microscope apparatus of the invention of the application includes an X-ray generator for generating incident X-rays, a sample stage for setting a sample, and a collimator as means for suppressing the angle divergence of diffracted X-rays.
- the sample and the two-dimensional X-ray detector are brought as close as possible through a collimator.
- the major feature of this method is that it suppresses angular divergence and measures and images diffracted X-rays while both the two-dimensional X-ray detector and the sample stage remain stationary without moving.
- “to bring the sample and the two-dimensional X-ray detector as close as possible through a collimator” means that the sample and the two-dimensional X-ray detector are as close as possible to the extent that the optical path of the incident X-ray irradiating the sample is not obstructed This means that the X-ray detector is approached via a collimator, and between the sample and the 2D X-ray detector (or between the sample and the collimator if the 2D X-ray detector is equipped with a collimator). This does not limit the concrete numerical value of the distance itself.
- the lower limit of the distance between the sample and the collimator attached to the two-dimensional X-ray detector is generally lower than the size of the incident beam on the upstream side in the direction of incidence of the incident X-rays on the sample.
- the same distance is required and a force of about 0.3 mm to 1 mm can be applied, and the downstream side can approach the distance determined by the thickness of the collimator and the CCD window.
- the spatial resolution is exactly the same for diffracted X-rays and fluorescent X-rays.
- the intensity of fluorescence X-rays and that of diffraction X-rays have different dependencies, and the effect of shortening the distance is greater with fluorescent X-rays. Therefore, when fluorescent X-rays have an undesired effect as a strong background, it may be necessary to increase the distance.
- the upper limit at that time depends on the intensity of the diffracted X-rays observed.Therefore, attention is paid to the intensity of the X-ray source, the crystallinity of the sample, Although it is a case-pi case due to the reflective surface, the distance can be typically up to about 10 mm. In this case, it is possible to acquire an image with an improved signal-to-background ratio while slightly sacrificing the spatial resolution.
- the collimation image can be obtained even if it is not built into the two-dimensional X-ray detector. Although it does not matter, it is desirable to be integrated with the two-dimensional X-ray detector, and it is desirable to be built-in, in order to make the distance as close as possible and save unnecessary space.
- X-rays with higher energy than the absorption edge are removed by a mirror or the like. Do not use high energy X-rays, which generate fluorescent X-rays by lowering the fluorescent X-rays. If the energy of the fluorescent X-rays is lower than that of the diffraction X-rays, an absorber is placed in front of the detector. Focusing on the difference between fluorescent X-rays and diffraction X-rays with respect to the distance between the sample and the detector, by placing a polymer thin film with a thickness of about 0.1 to 100 im. It may be possible to slightly increase the distance between the sample and the detector so that fluorescent X-rays do not enter the detector.
- the single-photon counting method can be adopted, the energy of X-rays entering the two-dimensional X-ray detector can be identified, and fluorescent X-rays and diffraction X-rays can be identified. Have different energies, even if they physically leave the same place As long as the imaging can be performed separately. For this reason, extremely strong fluorescence
- X-rays of 13 keV or more pass through the collimator built in a two-dimensional X-ray detector such as a CCD camera, creating an image that creates a correspondence between the sample and the CCD element surface. Since it becomes difficult, it is preferable to remove them. It is desirable to use an X-ray generator that generates continuous X-rays that do not contain high energy components of 13 keV or more.
- the X-ray diffraction can improve the resolution of X-ray diffraction, and a high-energy component removal optical system that removes high-energy components of 13 keV or more in incident X-rays can be used for incident X-ray samples. By arranging it closer to the X-ray generator than the incident position, high-energy components of 13 keV or more can be removed, and the resolution of X-ray diffraction can be further improved.
- the two-dimensional X-ray detector since the two-dimensional X-ray detector has only the detection elements arranged as it is, it is not possible to distinguish between X-rays that enter vertically and X-rays that jump in from the side, and the image is blurred and the positional resolution is reduced
- a collimator inside the two-dimensional X-ray detector it is possible to limit the direction of scattered X-rays entering the detection element and to detect only diffraction at the desired diffraction angle: X-rays. Further, it is possible to improve the position resolution.
- any one of a CCD camera and a CMOS image sensor having X-ray detection capability can be suitably used.
- the amount of electric charge generated in the CCD camera or the CMOS image sensor By determining the energy of the diffracted X-rays from, it is possible to obtain a high-quality image corresponding to the specific lattice spacing of the sample.
- CMOS image sensors are always assumed to be used in a manner similar to CCD cameras, CMOS image sensors have different CMOS image sensor principles. It consists of a one-dimensional or two-dimensional array element.
- the readout of the CMOS image sensor is much faster than that of the CCD, and if a large number of X-ray-sensitive CMOS image sensors are to be supplied in the future, the application of the present invention will probably be from the CCD to the CCD.
