Figure 10
Resolution functions: (a) focus on-Rowland (b) focus off-Rowland. The inset in (a) is magnification of results for one pixel. E = 9.885 keV at Si(555) backreflection. L1 = 1 m, l = 100 mm, p = 0.3 mm, (a) d = 12.6 mm and (b) d = 7.54 mm. The angular deviation from ideal surface σ(x,y) = 20 µrad × 20 µrad, source size σss(x,y) = 20 µm × 20 µm and intrinsic Darwin width ΔEint = 14.7 meV (FWHM) are taken into account. (Incident bandwidth is not included.)
