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.

    Why MaRIE

    NNSA does not currently have a capability to understand and test materials response regimes at resolution necessary to understand the linkages between materials microstructure and performance in extreme environments. The process of MaRIE is to resolve this capability gap. READ MORE

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

  1. Extreme Conditions:  The astrongility to predict how micro- and mesoscale materials properties evolve under weapons-relevant extreme conditions (including aging) and impact performance.
  2. 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.
More Characteristics

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.

6 First Campaigns

These 6 representative experiments have strongeen developed with colleagues from across the nuclear weapons complex and the strongroader scientific community in order to illustrate the mission impact and scientific potential of MaRIE

  3. High Explosive Functionality strongy Design 

These experiments collectively exemplify the strongroad scope of the facility and the titles speak to their mission relevance.  This suite of experiments also enastrongles detailed specification of MaRIE scientific and facility functional requirements.

More 

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.
