(a) Simulated reflectivity curve [I_{\rm R}(\Delta k)] for the (220) reflection in symmetric Laue geometry of a 100 µm-thick diamond single crystal at 12 keV. (b) Transverse echo signals S(x) at the five points along the reflectivity curve shown in (a). The energy deviation from the maximum diffraction condition is indicated. The blue dots are the data extracted from the simulated images, while the red curves are the modelled Gaussian multi-peak function [equation (11[link])]. (c) Same as (b) for the on-diffraction condition point (3) but in vertical logarithmic scale. The positions of the direct-beam hump (0th-order echo) and of the transverse echoes are indicated.
