Figure 3
Rocking-curve topographs for the large diamond plate, which was chosen as the 111 Bragg reflector in the high-heat-load monochromator of beamline 3B. The topographs show peak position (δθm) and curve width (Δθ). The dashed rectangle (∼8.5 × 1.8 mm) shows a region of reasonably good quality. The projection of the 111 reciprocal vector on the surface of the plate is shown with a black arrow (3.3° miscut). |
