DIAD is a dual beam instrument capable of imaging and diffraction at the same time at the micron scale.

With its unique design, DIAD will be delivering almost concurrent (chopped at a few Hz) imaging (~1 μm resolution) and diffraction (min. beam size ~10 μm) with the primary aim of relating 2- and 3D dynamic imaging of complex structures with monochromatic, Laue or SAXS micro-diffraction information (either strain mapping or phase identification). Other beamlines around the world can measure diffraction and imaging on the same sample via complicated mode changes or sample movements: DIAD will measure both concurrently.

DIAD’s unique dual beam design represents a step change in the possibilities of, for example, observing changes in shape AND stress state of structures during deformation and cracking, or determining morphology AND chemistry of phases during chemical reactions. Its medium-energy range (~7-37 keV) is ideally suited to imaging and diffraction of materials and biological applications where strain-induced transformations control microstructure, and microstructure controls mechanical, and many other types of performance.

Applications are wide-ranging, connecting fundamental scientific challenges with practical applications through examples such as osteoporosis, tissue scaffolds, asthma, plant roots, fossils, earthquakes, extraterrestrial materials, carbon sequestration, Li batteries, self-healing materials, polymer matrix composites, nuclear waste, coffee and personal care products.
