Abstract: Apparatus for X-ray analysis has a combination of a rotating target X-ray tube and a composite monochromator. The composite monochromator has a first and a second elliptic monochromators joined with each other side by side. Each of the elliptic monochromators has a first focal point at which an X-ray focal spot on a target of the X-ray tube is disposed. Each of the elliptic monochromators has a synthetic multilayered thin film whose d-spacing varies continuously along an elliptic-arc. The shortest distance between the X-ray focal spot and the composite monochromator is set to 40 to 100 mm. Under the shortest distance condition, the effective focal spot size on the target is set to 40 to 100 micrometers to obtain the maximum X-ray intensity on a sample to be analyzed.

Abstract: High-resolution powder diffraction is performed using high-energy synchrotron radiation as an x-ray source in such a way that a detector mounted on a measuring instrument such as a diffractometer is moved by smaller distances than the distance between adjacent x-ray detection units (pixels) in order to measure data for interpolation between pixels and the obtained interpolating data are put together to thereby improve the spatial resolution in measurement that has been limited by the detection unit in the detector.

Abstract: An incident monochromator and a microfocus X-ray source with an apparent focal spot size of less than 30 micrometers are combined so that the X-ray source can be close to the monochromator and the intensity of X-rays focused on a sample is greatly increased. A side-by-side composite monochromator is arranged between the X-ray source and the sample. The composite monochromator has a first and a second elliptic monochromators each having a synthetic multilayered thin film with graded d-spacing. The first elliptic monochromator has one side which is connected to one side of the second elliptic monochromator. A preferable apparent focal spot size D of the X-ray source may be 10 micrometers. Because the invention provides a high focusing efficiency for X-rays, it is not required to use a high-power X-ray tube. The X-ray tube according to the invention, moreover, may have a stationary-anode, whose power may be about 7 Watts.
