Schematic of a coherent diffraction beamline equipped with a monochromator that can be translated into and out of the white beam. (a) With the monochromator in the white beam, a coherent monochromatic beam is delivered to the sample, and a typical coherent diffraction pattern is measured when a nanocrystalline sample and area detector are positioned to satisfy a Bragg condition. (b) With the monochromator positioned out of the beam, a white-beam coherent diffraction pattern can be measured that surveys the orientation and size of multiple crystals illuminated with the beam. |
