Query: High-energy coherent X-ray diffraction microscopy of polycrystal grains:
  first steps towards a multi-scale approach   We present proof-of-concept imaging measurements of a polycrystalline
material that integrate the elements of conventional high-energy X-ray
diffraction microscopy with coherent diffraction imaging techniques, and that
can enable in-situ strain-sensitive imaging of lattice structure in ensembles
of deeply embedded crystals over five decades of length scale upon full
realization. Such multi-scale imaging capabilities are critical to addressing
important questions in a variety of research areas such as materials science
and engineering, chemistry, and solid state physics. Towards this eventual
goal, the following key aspects are demonstrated: 1) high-energy Bragg coherent
diffraction imaging (HE-BCDI) of sub-micron-scale crystallites at 52 keV at
current third-generation synchrotron light sources, 2) HE-BCDI performed in
conjunction with far-field high-energy diffraction microscopy (ff-HEDM) on the
grains of a polycrystalline sample in an smoothly integrated manner, and 3) the
orientation information of an ensemble of grains obtained via ff-HEDM used to
perform complementary HE-BCDI on multiple Bragg reflections of a single
targeted grain. These steps lay the foundation for integration of HE-BCDI,
which typically provides a spatial resolution tens of nanometers, into a broad
suite of well-established HEDM methods, extending HEDM beyond the
few-micrometer resolution bound and into the nanoscale, and positioning the
approach to take full advantage of the orders-of-magnitude improvement of X-ray
coherence expected at fourth generation light sources presently being built and
commissioned worldwide.
