Overview

The Plasma Physics Division conducts broad theoretical and experimental programs of basic and applied research in plasma physics, laboratory discharge, and space plasmas, intense electron and ion beams and photon sources, atomic physics, pulsed power sources, laser physics, advanced spectral diagnostics, and nonlinear systems. 

The effort of the Division is concentrated on a few closely coordinated theoretical and experimental programs. Considerable emphasis is placed on large-scale numerical simulations related to plasma dynamics; ionospheric, magnetospheric, and atmospheric dynamics; nuclear weapons effects; inertial confinement fusion; atomic physics; plasma processing; nonlinear dynamics and chaos; free electron lasers and other advanced radiation sources; advanced accelerator concepts; and atmospheric laser propagation.

Core Capabilities 

  • Radiation Hydrodynamics - The principal emphasis is in the development and application of theoretical models and state-of-the-art numerical simulations combining magnetohydrodynamics, high energy density physics, atomic and radiation physics, and spectroscopy.
  • Laser Plasma - Primary areas of research include physics underpinnings of laser fusion, high-energy-gain laser-inertial- fusion target designs, experiments and simulations of laser-matter interactions at high intensity, advancing the science and technologies of high-energy krypton fluoride and argon fluoride lasers, advancing the technologies of durable high-repetition-rate pulse power and electron-beam diodes for laser pumping and other applications, laser fusion as a power source.
  • Space and Laboratory Plasmas - Space research includes theoretical, numerical, and laboratory and space experimental investigations of the dynamic behavior of the near-Earth space plasmas and radiation belts, and the modification of space plasmas for strategic effects on HF communications, satellite navigation, over-the-horizon radar, and UHF satellite communications.  Applications-oriented plasma research is performed in the production, characterization, and use of low-temperature plasmas and related technology for applications to advance capabilities across the Navy and DOD.  Pulsed-power investigations include electromagnetic launch science and technology and research on directed energy systems for the U.S. Navy.
  • Pulsed Power Physics - Experimental and theoretical research is performed to advance pulsed power driven accelerator technology in areas relevant to defense applications. Research concerns the production, transport, characterization, and modeling of pulsed plasmas and intense high-power, charged particle beams using terawatt-class hundred-kilojoule pulsed power systems that employ capacitive or inductive energy storage and advanced switching. 
  • Directed Energy Physics - Research encompasses the integration of theoretical/computational and experimental research relevant to DOD, ONR, DARPA, and DoE in the areas of ultra-high field laser physics, atmospheric propagation of intense lasers, advanced radiation and accelerator physics, laser-generated plasma-microwave interactions, and dynamics of nonlinear systems.

NRL Principal Scientist John Michopoulos Received the Robert Moskovic Award

By Nicholas E. M. Pasquini, U.S. Naval Research Laboratory Corporate Communications

U.S. Naval Research Laboratory (NRL) mechanical engineer, John Michopoulos, Ph.D., received the 2022 Robert Moskovic Award from the European Structural Integrity Society (ESIS) in recognition of his outstanding contribution to the fields of computational, theoretical and experimental multiphysics.

“Dr. Michopoulos’ research has been focused on how best to advance the state of the possible, including changing basic paradigms of materials research, to enhance DOD platform performance including enabling new capabilities,” said Material Science and Technology Division Superintendent Virginia DeGiorgi, Ph.D, SES. “This award is extremely important in that it is recognition by an outside community of the efforts led by Dr. Michopoulos at NRL in the development of theoretical understanding and computational tools required for advanced design and risk mitigation.”

The Robert Moskovic Award distinguishes individuals with scientific and academic careers that have earned recognition from their peers worldwide. The prize is a tribute to the founder of the ESIS-Technical Committee on Risk Analysis and Safety of Large Structures and Components (TC12). Moskovic created a distinguished career in the nuclear power industry, where he developed radical new systems for the safety of reactors.

“I am extremely humbled and honored that the ESIS-TC12 recognized the significant value of the work my colleagues and I have been conducting here at NRL,” said Michopoulos. “I feel that the impact our research has had on the Navy and the material science communities is based on the enduring contributions of technologies developed by the Computational Multiphysics Systems Laboratory.”

As NRL’s Principal Scientist of Material Innovation within the Material Science and Technology Division, Michopoulos, founded and is actively involved with the Computational Multiphysics Systems Laboratory (CMSL) established in 1999. The CMSL addresses the realities of materials beyond physical space into the conceptual and computational spaces resulting in the data-driven systemic behavior prediction of complex systems including composite materials and platforms.

For nearly 38 years, Michopoulos has provided enabling technologies to the continuum systems modeling and composite materials communities such as computationally enabled efficient, inexpensive and reliable methodologies for addressing the needs of system builders, qualifiers, certifiers, and operators.

“NRL is the birthplace of many advances in fracture mechanics, rational continuum mechanics, and proposed the use of nuclear power to propel submarines,” Michopoulos said. “Our group is responsible for the only automated methodology that experimentally determines the full constitutive behavior materials both in the linear and non-linear regimes. This involves high throughput robotic multiaxial testing, coupled multiphysics based machine learning approaches for solving inverse problems for the constitutive characterization of materials and high performance non-contact full-field displacement and strain field methods."

The CMSL group is automating the process of generating custom data-driven simulation environments and digital twins that provide access to the measured behavior of materials and manufacturing processes (e.g. additive manufacturing) capable of spanning multidimensional multiparametric spaces related to Naval system design, qualification, and sustainment.

Consequently, Michopoulos oversees the development of computational methodologies and systems enabling design and systemic tailoring to desired behavior of systems and structures under multiple generalized loading conditions, including mechanical, thermal, environmental, and electromagnetic.

His materials research and expertise remains relevant for assets throughout the Navy in regard to designing, manufacturing, qualifying and repairing, including aircraft, ships, submarines, space platforms, and civil infrastructure and transportation systems.

The Materials Science and Technology Division conducts basic and applied research in functional and structural materials and engages in exploratory and advanced development to generate new Navy technologies and defense capabilities. 

These efforts are performed by multidisciplinary teams of materials scientists, physicists, chemists, and engineers working at the atomic, nano, microstructural, mesostructural, and macroscopic scales.

The integrated use of new experimental and computational techniques accelerates new scientific understanding and innovative engineering solutions. Advanced materials synthesis, processing, characterization, diagnostic capabilities, performance prediction methods, and life-cycle management methods are developed to further new device design, prototyping, and testing methods.
