Section: claims

1. An X-ray optical configuration for irradiation of a sample, the configuration generating an X-ray beam having a line-shaped cross-section, the configuration comprising:a brilliant X-ray point source; anda beam-conditioning X-ray optics, said X-ray optics comprising an X-ray optical element for conditioning X-ray radiation emitted by said point source in such a fashion that the X-ray beam is rendered parallel in a direction perpendicular to a beam propagation direction and remains divergent in a direction which is perpendicular thereto and also to the beam propagation direction. 2. The configuration of claim 1, wherein an aspect ratio AQ of said point source is 1≦AQ≦1.5 and an aspect ratio AS of a beam cross-section in an area of the sample is AS≧2. 3. The configuration of claim 1, wherein said X-ray optical element comprises a Kirkpatrick-Baez mirror system. 4. The configuration of claim 1, wherein said X-ray optical element comprises a Montel mirror system. 5. The configuration of claim 1, wherein said X-ray optical element is structured to rotate about an axis of said beam propagation direction. 6. The configuration of claim 5, wherein said X-ray optical element can be rotated about the axis of said beam through 90°. 7. The configuration of claim 1, wherein said brilliant point source comprises a rotating anode and a microfocus source or a liquid metal configuration. 8. The configuration of claim 1, further comprising a collimator disposed in an area of the sample for collimating-down the X-ray beam, having a line-shaped cross-sectional profile, to a beam profile with point-shaped beam cross-section. 9. The configuration of claim 1, wherein focussing X-ray optics consists essentially of said X-ray optical element. 10. The configuration of claim 1, further comprising a monochromator disposed between said X-ray optical element and the sample. 11. An X-ray optical element structured for use in the X-ray optical configuration of claim 1, wherein the X-ray optical element is structured to image a point on a line focus. 12. An X-ray analysis device comprising the X-ray optical configuration of claim 1.
