Schematics of the rocking curve imaging (RCI) experiments. (a) Projection RCI with a millimetre-sized box beam illuminating the sample in reflection geometry. The 2D detector having 0.75 µm pixel size is positioned at 330 mm downstream of the sample. (b) Scanning section RCI with 10 µm-tall beam selected by the Au slits. The tungsten plate is placed close to the detector to block a part of the diffracted beam generated by the CZT substrate so that only the diffracted beam by MCT reaches the detector. The sample is translated along the beam, the x direction, as shown. (c) Reconstructed maps of integrated intensity, FWHM and peak position are generated using the rocking curve data. |
