White-beam X-ray topographs of the selected diamond (111) crystal plates: (a) 300 µm-thick plate (second monochromator crystal) and (b) 100 µm-thick plate (first monochromator crystal). The images are obtained from the diamond reflection in Laue geometry. The dotted boxes illustrate the 5 × 2 mm working regions, containing only a few defects. |
