Figure 8
Results in the vertical 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 vertical distance at the effective source located 28.8 m upstream of the grating. In the lower panel are shown (i) beamline data obtained by Talbot interferometry shown 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. |
