Figure 2
Concept and design parameters of the array of inclined RMLs for large FOV PSR-STHXM. (a) Top view. (b) Side view [d – distance between RMLs; Δdiff – diffraction-limited spot size; FOVh and FOVv – horizontal and vertical FOVs in the detector plane, respectively; Fi (i = 1, 2, …, N) – the distances of focal positions measured from RML1; w – web distance; Aph – physical aperture; R – radius of curvature; b – distance between neighboring parabolas; α – tilt angle of the substrate; β – inclination angle of the RML against the substrate; Ld – length of the lens; Lcross – lens length along with X-rays; h – height of the structures when the substrate is tilted; t – transition zone where two RMLs contribute to form line foci; dl – depth of field; NV – number of lenses in each RML]. |
