Figure 9
Results in the horizontal plane at 8.500 keV for the two-reflection geometry which is for a beam directly exiting the DCM. In the upper panel is shown the result obtained with the SHADOW ray-tracing program. It shows the profile of the intensity versus horizontal distance at the effective source, that is, at the bending magnet located 35.5 m upstream of the grating. In the lower panel are shown (i) beamline data obtained by Talbot interferometry as points together with dashed lines that connect these points, (ii) simulated Talbot interferometry as a solid light line, and (iii) the CCF, calculated from the profile shown in the upper panel, as a solid heavy line.
