Los Alamos National Laboratory has defined a new signature science facility, Matter-Radiation Interactions in Extremes (MaRIE) that builds on the existing capabilities of the Los Alamos Neutron Science Center (LANSCE). It will be the first multi-probe materials research center to combine high-energy, high-repetition-rate, coherent x-rays with electron and proton-beam charged-particle imaging to perform in-situ measurements of a sample in extreme environments. At its core, a 42-keV XFEL will be coupled with the LANSCE MW proton accelerator. A pre-conceptual design for MaRIE has been established. Technical risk reduction for the project includes an injector test-stand that is currently being designed. New accelerators are either planned, under construction, or currently in operation around the world, providing opportunities for the MaRIE project to leverage the instrumentation & controls (I&C) efforts of these facilities to minimize non-recurring engineering costs. This paper discusses possible MaRIE I&C system implementation choices and trade-offs, and also provides an overview of the proposed MaRIE facilities and the current design.
