HEW as function of Δf1 and Δf2 for the vertical K–B mirror (λ = 20 nm). (a) Ideal profile. (b) Real profile. Solid white line: interpolating function . White dots: minima computed for values of Δf1 corresponding to the position of radiators II–VI. Dashed light blue line: equation (5), computed for continuous values of Δf1. Inset: profiles of the HEW taken along Δf2 for = −3.75 m (corresponding to radiator V). Solid black line: ideal mirror. Dashed black line: real mirror. See description in the text. |
