(a) Schematic of the double-crystal rocking curve imaging technique. (b) Measured and calculated double-crystal rocking curve of a cryogenic Si (111) monochromator (left inset). Crystal dimension 40 mm (L) × 15 mm (W) × 95 mm (H) (right inset). The X-ray footprint on the crystal is about 35 mm × 12 mm during measurements. (c) The distribution map of midpoints of local rocking curves extracted from rocking curve images recorded by a CCD camera with 4096 × 4096 pixels (pixel size 2.6 µm). Si 333 reflection. E = 8.05 keV. σ-polarization.
