(a) DuMond diagram for bent R = 250 mm Si crystals for different (n,n,0) and (n,n,n) lattice planes. Shaded areas represent the energy window covered by the analyzer crystals. (b)–(i) Calculated (colored) and experimental (thin dashed) reflectivity curves between ca. 6 and 17 keV. All theoretical reflectivity curves were obtained by solving the 1D Tagaki–Taupin equations (Takagi, 1962BB37, 1969BB38; Taupin, 1964BB39) using the pyTTE package by Honkanen & Huotari (2021BB12).
