Abstract:  A scientific revolution is occurring in how materials are studied dynamically at the mesoscale that is broadly defined as the gap between the quantum frontier at the nanometer scale and the realm of continuum mechanics at the macroscale. This revolution is being enabled by two critical new technologies: (1) astonishing increasing in X-ray brilliance from accelerator based sources and (2) coherent X-ray imaging and scattering techniques. In this talk, we will review the rapidly developing technologies that are enabling this revolution in materials science, the state of the art application of coherent X-ray imaging to dynamic materials processes, and the need for increased hard X-ray (>40 keV) coherent flux in order to make 'mesoscale movies'. Additionally we will briefly overview multiple current LANL efforts to apply these brilliant X-ray sources and coherent X-ray techniques to critical mission applications. Finally, we will address the vision and the challenge of the proposed MaRIE facility at LANL that will enable mesoscale movies of mission critical materials dynamics.
