Query: Combining Laue diffraction with Bragg coherent diffraction imaging at
  34-ID-C   Measurement modalities in Bragg coherent diffraction imaging (BCDI) rely on
finding signal from a single nanoscale crystal object, which satisfies the
Bragg condition among a large number of arbitrarily oriented nanocrystals.
However, even when the signal from a single Bragg reflection with (hkl) Miller
indices is found, the crystallographic axes on the retrieved three-dimensional
(3D) image of the crystal remain unknown, and thus, localizing in reciprocal
space other Bragg reflections becomes in reality impossible or requires good
knowledge of the orientation of the crystal. We report the commissioning of a
movable double-bounce Si (111) monochromator at the 34-ID-C end station of the
Advanced Photon Source, which aims at delivering multi-reflection BCDI as a
standard tool in a single beamline instrument. The new instrument enables this
through rapid switching from monochromatic to broadband (pink) beam permitting
the use of Laue diffraction to determine crystal orientation. With a proper
orientation matrix determined for the lattice, one can measure coherent
diffraction near multiple Bragg peaks, thus providing sufficient information to
image the full strain tensor in 3D. We discuss the design, concept of
operation, the developed procedures for indexing Laue patterns, and automated
measuring of Bragg coherent diffraction data from multiple reflections of the
same nanocrystal.
