Abstract
For a quasi-monochromatic x-ray radiation with high radiation intensity, an x-ray radiator generates quasi-monochromatic x-ray radiation to expose a subject from a point-shaped radiation source that emits a polychromatic x-ray radiation, and having a diffraction device to diffract the polychromatic x-ray radiation. The diffraction device has a super-mirror made of crystalline material with a flat surface. In the super-mirror, the crystalline material has at least one (in particular continuous) variation of the lattice plane spacing of the crystal lattice. The radiation source and the diffraction device are arranged such that quasi-monochromatic x-ray radiation is generated from the polychromatic x-ray radiation by partial reflection at the super-mirror.
