Characterization of the X-ray wavefront upon Bragg diffraction from selected diamond crystals. (a) Schematic of the experimental setup on APS beamline 1-BM with a reference crystal Cr and a sample crystal Cs. (b)–(d) Measured X-ray wavefront phase error maps for the selected diamond crystals C2, C3 and C4, respectively. (e)–(g) Distribution of the r.m.s. phase errors in 100 µm × 100 µm regions of the corresponding crystals. The minimum, median and mean r.m.s. phase errors are shown in each graph. |
