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 researcher receives ASME Lifetime Achievement Award

By Michelle Patten, U.S. Naval Research Laboratory Corporate Communications

John Michopoulos, Ph.D., U.S. Naval Research Laboratory’s (NRL) Computational Multiphysics Systems Laboratory head, received the American Society of Mechanical Engineers (ASME) Computers and Information in Engineering (CIE) Lifetime Achievement Award.
 
The award was presented Aug. 15, during a ceremony at the International Design Engineering Technical Conferences and CIE Conference in St. Louis, Missouri, and is the highest award bestowed by the ASME CIE division. The award’s commendation is, “In recognition of outstanding lifetime achievements in advancing the discipline of computers and information in engineering.”
 
“Doctor Michopoulos has been a vital part of NRL’s mission since 1986,” Virginia DeGiorgi, Ph.D., superintendent of NRL’s Materials Science and Technology Division said. “He has always been willing to address new and emerging problems, never satisfied to rest on his laurels.”
 
Among the many accomplishments credited to Michopoulos is the development of the first autonomous recursive six degrees of freedom (6-DoF) robotic testing system. This system was designed to generate all the necessary material response data for physics-based machine learning to characterize their response and test materials under loading emulating in-service conditions.
 
At NRL ongoing extensions of this technology enable studying multiaxial and multiphysics fatigue of materials. Michopoulos and his group also created forward and inverse multiphysics and multiscale theories and machine learning models along with the associated computational tools and methodologies to generate digital twins for the characterization, performance prediction, qualification and certification of many material systems and platforms including those produced by the additive manufacturing processes in the spirit of Integrated Computational Materials Engineering principles.
 
“As an example, our group [the Computational Multiphysics Systems Laboratory] has developed technology that performs multiscale morphology optimization,” Michopoulos said. “This determines the shape of structures that is the best possible for performing multiple functions. It allows us to tailor the shape and morphology of a part for maximizing a desired performance.”
 
Michopoulos credits his early curiosity and inspiration in the field of science and engineering to the mentors he had starting from a young age.
 
“I was fortunate to have teachers and mentors who inspired me and fertilized my desire to pursue a career of trying to answer questions in science and technology, and do it in such a way that obstacles should not be considered as difficulties but rather as opportunities,” Michopoulos said.
 
Mentorship continues to play a key role in Michopoulos’ career with both students and colleagues. He has held leadership roles throughout ASME’s CIE division, serving on the CIE Executive Committee from 2008-2013. He has chaired the 2011 CIE conference and has co-chaired the 2012 CIE conference, organizing numerous workshops and sessions in them and all subsequent conferences.
 
“In addition to his technical accomplishments, he has used his skills as a teacher, mentor and collaborator to develop the next generation of scientific leaders for NRL,” DeGiorgi said.
 
Other notable achievements in the course of Michopoulos’ career are the publication of four books, 15 peer-reviewed book chapters, 91 peer-reviewed journal publications, 259 peer-reviewed conference papers, and 10 patents.
 
In addition to being recognized as a fellow of the ASME (2013), he has been honored with numerous scientific excellence and leadership awards, to include, the P.S Theocaris Award from the National Academy of Athens in 2013, the 2014 Wolfram Innovator award from Wolfram Research, Inc., ASME’s 2015 Excellence in Research Award, and the 2021 Sigma Xi Edison Chapter award for Applied Sciences.
 
His collaboration with industrial partners for several applied sciences projects has been demonstrated via multiple Cooperative Research and Development Agreements where the research products of the group have been and are being transitioned to practice within Department of Defense interests.
 
“Awards like the Lifetime Achievement Award may seem to provide a validation that others find your efforts useful, but they are not capable of revealing the incredible collaboration and synergy within the Computational Multiphysics Systems Laboratory members, who have all contributed to the successes led to this award,” Michopoulos said. “Really this award is a reflection of not just my work, but also the work of all nine members of the group, plus the unwavering support of my family.”
 
Michopoulos maintains his dedication to education by serving as a mentor to many Naval Research Enterprise Intern Program students and summer faculty.
 
He offered this advice for early career researchers, “Find the dream or goal that scares you. A goal that you feel is impossible in so many ways, and then go after it. You’ll be pleasantly surprised about what you can achieve when you aim higher than you think you can achieve.”
 
Founded in 1880, ASME is a not-for-profit membership organization with over 90,000 members worldwide that enables collaboration, knowledge sharing, career enrichment, and skills development across all engineering disciplines. The goal and mission of ASME is to help the global engineering community develop solutions to benefit lives and livelihoods and promote the art, science and practice of mechanical and multidisciplinary engineering and allied sciences to diverse communities throughout the world.
