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-Developed Micro-UAV Named POPULAR SCIENCE 'Best of What's New'

By Daniel Parry

The small glider Close-in Covert Autonomous Disposable Aircraft (CICADA) developed by U.S. Naval Research Laboratory (NRL) aerospace engineers, Aaron D. Kahn and Dr. Daniel J. Edwards, has been named '2015 Best of What's New' by the distinguished science and technology publication, POPULAR SCIENCE.

The CICADA unmanned aerial vehicle (UAV) is a low-cost, GPS-guided micro disposable air vehicle that can be deployed in large numbers. Having no source of propulsion onboard, the small craft is released from another airborne platform at altitude and the CICADA then glides to its destination. Its lack of a motor and small size makes it nearly undetectable in flight.

Essentially a flying circuit board, CICADA is inherently stable in glide and is designed for launch from manned or unmanned aircraft, balloons, or precision guided munitions, Edwards says. After deployment, CICADA glides to a waypoint, enters an orbit, and then descends within that orbit until it reaches the ground, typically landing with an average error of fifteen feet from the commanded orbit.

Having a 3.5 to 1 glide ratio, CICADA allows sensors to be deployed at very comfortable standoff distances. In the air, meteorological, chemical, or biological measurements can be taken, quickly sampling a large volume of the sky. Once on the ground, communication nodes will be established.

The POPULAR SCIENCE 28th Annual Best of What's New Award nominates ideas that are revolutionary, that transform their category, solve an unsolvable problem, and incorporate entirely new ideas, and functions, i.e., the product or technology must exist and must be demonstrable and testable.
