Calculated reflectivity curves of two circular Si(555) SBCAs with bending radii of 0.5 m and 1 m at two different Bragg angles in comparison with experimental curves (Rovezzi et al., 2017BB50). The wafer diameters were 100 mm and the thicknesses 150 µm. The centroid energy of the theoretical curves were adjusted separately for 1 m and 0.5 m analysers. The ratio of theoretical integrated intensities of the two SBCAs were scaled according to their solid angle multiplied with their integrated 1D Takagi–Taupin reflectivities.
