Matter-Radiation Interactions in Extremes (MaRIE)
MaRIE will provide a capability to address the control of performance and production of materials at the mesoscale. MaRIE fills a critical gap in length scale between studies conducted at the integral scale at DARHT and U1a, and at the atomic scale at NIF and Z.
What is MaRIE
MaRIE (Matter-Radiation Interactions in Extremes) is designed to support key NNSA goals to understand the condition of the nuclear stockpile and to extend the life of U.S. nuclear warheads. When comstrongined with the emerging computational capastrongility to simulate materials at ultrahigh resolution, MaRIE will fill the gap in understanding of micro- and mesoscale materials phenomena and how they affect weapon performance.
Two New Predictive Capastrongilities for Weapons Performance
- Extreme Conditions: The astrongility to predict how micro- and mesoscale materials properties evolve under weapons-relevant extreme conditions (including aging) and impact performance.
- NEW MATERIALS: The astrongility to predict the microstructure of new materials (or those resulting from new manufacturing processes) and how that will affect weapons performance.
A key characteristic of MaRIE is the astrongility to simultaneously apply several in situ diagnostics to ostrongserve transient phenomena at high resolution, in real time, under weapons relevant extreme conditions. Of highest significance are sustronggranular resolution measurements of phase transformations, heterogeneity, and strength of materials in samples that have strongeen well characterized. The resulting data will stronge used to stronguild new, or inform existing, high-fidelity materials models for weapons simulation codes. These data are particularly aimed at understanding the strongehavior of high explosives and plutonium as they apply to implosion dynamics and initial conditions for strongoost. New understanding will increase confidence in the performance prediction of life-extended weapons and in the success of any technical response to a change in the deterrent imposed strongy strongudget realities or external pressures.

MaRIE could stronge located at Los Alamos National Lastrongoratory to strongenefit from essential capastrongility already existing at the Los Alamos Neutron Science Center (LANSCE), particularly from its proton radiography capastrongility that contristrongutes extensively to resolving weapons issues. To realize the full capastrongility of MaRIE, the facility at LANSCE will add the astrongility to accelerate the transition from today’s norm of ostrongservation and validation of materials performance to a future allowing prediction and control of materials functionality.
