The MaRIE Core Team included Cris Barnes, Mark Bourke, Pat Colestock, Micheline Devaurs, Paul Dunn, John Erickson, Dave Funk, Turab Lookman, T.

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. 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 combined with the emerging computational capability 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. Extreme Conditions: The ability to predict how micro- and mesoscale materials properties evolve under weapons-relevant extreme conditions (including aging) and impact performance. NEW MATERIALS: The ability 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 ability to simultaneously apply several in situ diagnostics to observe transient phenomena at high resolution, in real time, under weapons relevant extreme conditions. Of highest significance are subgranular resolution measurements of phase transformations, heterogeneity, and strength of materials in samples that have been well characterized. The resulting data will be used to build new, or inform existing, high-fidelity materials models for weapons simulation codes. These data are particularly aimed at understanding the behavior of high explosives and plutonium as they apply to implosion dynamics and initial conditions for boost. 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.

The Basic Energy Sciences Advisory Committee (BESAC) - established on September 4, 1986 - provides valuable, independent advice to the Department of Energy on the Basic Energy Sciences program regarding the… complex scientific and technical issues that arise in the planning, management, and implementation of the program. BESAC's recommendations include advice on establishing research and facilities priorities; determining proper program balance among disciplines; and identifying opportunities for interlaboratory collaboration, program integration, and industrial participation. The Committee primarily includes representatives of universities, national laboratories, and industries involved in energy-related scientific research. Particular attention is paid to obtaining a diverse membership with a balance of disciplines, interests, experiences, points of view, and geography. BESAC operates in accordance with the Federal Advisory Committee Act (FACA, Public Law 92-463; 92nd Congress, H.R. 4383; October 6, 1972) and all applicable FACA Amendments, Federal Regulations and Executive Orders. Over the course of this study the Mesoscale Science Subcommittee of the Basic Energy Sciences Advisory Committee engaged hundreds of colleagues in town hall meetings, webinars, and web site interactions in order to identify important and timely priority research directions for mesoscale science, as well as the capabilities required to address these challenges. This report outlines the need, the opportunities, the challenges, and the benefits of mastering mesoscale science. We are at a time of unprecedented challenge and opportunity. Our economy is in need of a jump start, and our supply of clean energy needs to dramatically increase. Innovation through basic research is a key means for addressing both of these challenges. The great scientific advances of the last decade and more, especially at the nanoscale, are ripe for exploitation. Seizing this key opportunity requires mastering the mesoscale, where classical, quantum, and nanoscale science meet. It has become clear that in many important areas the functionality that is critical to macroscopic behavior begins to manifest itself not at the atomic or nanoscale but at the mesoscale, where defects, interfaces, and non-equilibrium structures are the norm. With our recently acquired knowledge of the rules of nature that govern the atomic and nanoscales, we are well positioned to unravel and control the complexity that determines functionality at the mesoscale. The reward for breakthroughs in our understanding at the mesoscale is the emergence of previously unrealized functionality. The present report explores the opportunity and defines the research agenda for mesoscale science-discovering, understanding, and controlling interactions among disparate systems and phenomena to reach the full potential of materials complexity and functionality. The ability to predict and control mesoscale phenomena and architectures is essential if atomic and molecular knowledge is to blossom into a next generation of technology opportunities, societal benefits, and scientific advances.

Reports from several previous workshops are includes as appendices. The performance of materials in extreme environments is central to a number of national security challenges, including esp…ecially the need for sustainable energy solutions. From fission & fusion energy to nuclear weapons to a broad suite of renewable challenges, a science-based approach to certifying materials performance for extended lifetimes is needed. The need to develop materials that perform in new and more extreme environments is also acute. Put simply, we lack sufficient confidence in the materials we have to confidently predict or extend their lifetime. Materials often fail at one tenth or less of their intrinsic limit and we do not know why. 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. 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.
