Figure 3
Ray-tracing simulation of the intensity distribution in the transition area t of the inclined RML array (see Fig. 2[link]) made of nickel at an X-ray energy of 35 keV. The distance between two neighbor line foci is 24 µm, which is equal to the aperture of the lenses. (a) Perfect RMLs provide three parallel focus lines appearing in red with nearly no background feature. (b) The background feature is prominent when neighbor RMLs have a 2 µm height difference. Background features when the substrate is not perfectly inclined to α = 30°, but to (c) α = 29.8° and (d) α = 30.2°.
