“…[10][11][12][13] Explanations based on the geometric optics, normal wave-guide modes and the Fresnel-Kirchhoff diffraction theory have been given for a mono-capillary guide. [10][11][12][13][14][15][16] An interference-like fine structure of the intensity distribution of x-rays in a focal plane of a poly-capillary lens 10 has been explained by the interplay of geometrical factors, such as coherence length and capillary surface roughness, but not coherent interference. 16 Development of the highly monochromatic (longitudinally coherent) x-ray sources, such as x-ray lasers, 3 rd and 4 th generation synchrotron facilities, may provide the appropriate conditions for observation of the interference effects in a poly-capillary lens system.…”

The intensity distributions of the coherent and partially coherent x-rays passed through a poly-capillary lens have been computed at the focal plane. The computations showed that at the appropriate experimental conditions the interference phenomenon does affect the intensity distribution. In the case of the coherent input radiation with the photon energy of 0.1 keV, the interference fringes were observed, while the non-coherent x-ray radiation produced no interference-like intensity distributions.

Wave optics treatment of x-rays passing through tapered capillary guides

The propagation of soft x‐rays generated by a small‐diameter incoherent source through a tapered, plane capillary‐type waveguide was studied using the Fresnel–Kirchhoff theory and method of images. The diffraction and interference are manifested by the appearance of the diffraction fringes in both the near‐ and far‐field zones of the waveguide output. The experimental data confirm such behaviour of the x‐radiation. Copyright © 2000 John Wiley & Sons, Ltd.

The optical guiding of x-ray radiation by capillary waveguides is analysed by using the Fresnel-Kirchhoff diffraction theory and the method of images. The guiding of the continuous, short-pulse, coherent, partially coherent and incoherent waves is presented as the diffraction and interference of several x-ray beams produced in free space by the Fresnel source of the waveguide. Using the Fresnel source properties, the necessary conditions for influence of the diffraction and interference on the output characteristics of the capillary x-ray optics in the near-and far-field diffraction zones are derived. The experimental data and computer simulations presented confirm the wave optics behaviour of x-rays under such conditions.
