A Survey Of Current And Emerging Experimental Requirements For Dynamic Mesoscale Materials Science At User Facilities

There is a recognized need for a Dynamic Mesoscale Materials Science Capability (DMMSC) that enables characterization, production and control of matter in extreme conditions. Programs demanding this capability can have dramatically different requirements for instrumentation and sample environments, creating a unique challenge for experimental systems design. In order to leverage experience gained from dynamic experiments at existing facilities, input was obtained from the user community on design directions, desired functionality, and best practices. The consensus included needs ranging from accelerator developments to instrumentation advancements to improvements in facility user program processes and user experience. Presented here are brief reviews of some current facilities, expected changes due to upgrades, and a set of capabilities that the user community has identified as important to the future of high impact dynamic mesoscale materials science at user facilities.
