Experimental workflows on DIAD, post-processing, and analysis pipelines can all be automated using innovative in-house software. Users can access advanced data acquisition strategies, analyse their data live, and ultimately make informed decisions about their science to maximise the potential of their experimental time. DIAD saw its First Light in December 2018 and welcomed its first User in February 2021. Since then, it has hosted a wide range of users across several fields including, but not limited to: •
Medicine - The behaviour of arterial stents under changing pressure for better patient outcomes • Environment: The dynamic study of plant root behaviour in climate change affected soils
...
Energy – The operando spatial distribution of charge in Li-ion batteries. •
Materials – Stress induced cracking in nuclear containment materials. In summary, users can simultaneously collect time- and spatially-resolved information on both the crystallographic micro-structure and material macrostructure.
Space - Examining the mineralogy of samples returned from the asteroids Ryugu and Bennu
The DIAD beamline has the unrivalled capability to access multiscale, multi-modal information, granting users the ability to investigate highly dynamic systems.
