Schematic of the setup with the X-ray source, lens, waveguide and detector. The lens aperture can be set by an adjustable horizontal slit in front of the lens. Five planes Si are defined, as well as the distances Rij between the source, lens, waveguide and detector. The distance between points xi in plane Si and xj in plane Sj is sij. The subscripts i in the coordinates xi in the text refer to the subscripts of the corresponding planes Si. |
