Abstract Scope	Crystalline materials properties depend on their nanoscale structure. In micron to nanometer scale dimensions, knowing the crystallographic orientation and full strain tensor can predict the mechanical properties of particles and crystal grains of polycrystalline metals. Bragg coherent x-ray diffraction imaging allows the visualization of the local atomic lattice displacement of single nanoparticles or grains in 3D. However, measurement modalities in Bragg coherent diffraction imaging broadly rely on a single crystalline grain satisfying the Bragg condition within a potentially large population of sub-micrometer scale crystals with unknown crystallographic orientations. We report the commissioning of a movable monochromator at the 34-ID-C end station of the Advanced Photon Source, which delivers multi-reflection BCDI and full strain tensor 3D imaging as a standard tool in a single beamline instrument. We discuss the design and concept of operation of the instrument, and show examples of materials science applications that would benefit from the new capabilities.
