Dynamic Mesoscale Material Science Capability

DMMSC will address the control of performance and production of materials at the mesoscale. The project formerly known as MaRIE will fill a critical gap in materials data in length scale between the integral scale at DARHT and U1a & 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.

What is DMMSC

The Dynamic Mesoscale Material Science Capability (the project formerly known as MaRIE [Matter-Radiation Interactions in Extremes]) is designed to support key NNSA goals and the 2018 Nuclear Posture Review to provide a modern, flexible, adaptable, tailored, effective, robust, resilient and ready stockpile while remaining at the forefront of science and technology to reduce the likelihood of technological surprise.  When combined with the emerging computational capability to simulate materials at ultra-high resolution, DMMSC will fill the gap in understanding of micro- and mesoscale materials phenomena and how they affect weapon performance.

Unique Characteristics of DMMSC

The first unique characteristic of the proposed capability would be high-energy x-rays sufficient to see into and through the mesoscale for all materials including high-Z strategic materials.  Second, it would have a very flexible and fast repetition rate coupled with ability to watch dynamic events throughout their evolution to make movies of important material phenomena.  Finally is the ability to simultaneously apply several in-situ diagnostics to observe transient phenomena at high resolution, in real time, under weapons relevant extreme conditions. The resulting data will be used to build new, or inform existing, high-fidelity materials models for simulation codes. 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 by budget realities or external pressures.

6 First Campaigns

These 6 representative campaigns are domains of material science where data is needed for stewardship.  The campaigns and the scientific requirements to study them have been developed with colleagues from across the nuclear weapons complex and the broader scientific community in order to illustrate the mission impact and scientific potential of DMMSC

As part of determination of mission need, Los Alamos National Laboratory developed the MaRIE concept as a plausible alternative that could meet all the requirements and could have its cost and schedule reviewed by the Department of Energy.  MaRIE could be located at Los Alamos National Laboratory to benefit from essential capability already existing at the Los Alamos Neutron Science Center (LANSCE), particularly from its proton radiography capability that contributes extensively to resolving weapons issues as well as other accelerator infrastructure.
