Taking Bragg Coherent Diffraction Imaging to Higher Energies at Fourth Generation Synchrotrons: Nanoscale Characterization

High-energy Bragg coherent diffraction imaging (BCDI)can enablethree-dimensional imaging of atomic structure within individual crystallitesin complex environments. Here, we show that sufficient coherent photonflux is available to extend the BCDI technique to higher energiesto (1) obtain improved strain information and sensitivity at the nanoscalewith higher order Bragg reflections, (2) exploit BCDI in embeddedmaterials or complex operando environments, (3) reduceX-ray induced sample modification, and (4) minimize dynamical scatteringeffects. We demonstrate the nanoscale imaging technique on the samesub-micrometer sized crystal at 8.5, 19.9, and 33.4 keV by takingadvantage of the brilliance and coherence of the fourth generationExtremely Brilliant Source of the ID01 beamline at ESRF - The EuropeanSynchrotron (Grenoble, France). The photon flux, data quality, resolutionand strain information are compared. We also show the first coherentdiffraction measurements performed at the ID31-EBS beamline at anenergy of 41 keV.
