Figure 8
Energy resolution, Δλ/λ, for a beamline with diverging illumination on VLS gratings with (a) ideal and (b) fixed included angles estimated from the ray-traced spots, together with the source-size (dotted lines), slope-error [dashed lines in (a)] and defocus [dashed lines in (b)] limited resolutions. The total of the source-size and aberration (defocus, coma and spherical) limited resolutions (solid lines) is also plotted in (b).
