Support the development of electromagnetic systems that are pervasive and paramount to LLNL as service to DOE, DoD, and the greater National Security community.
LLNL has demonstrated world-class R&D using electromagnetic infrastructure capabilities and computational electromagnetic codes adaptable to new problems in these areas:
Workforce — A world-renowned workforce with integrated experimental, computational, and analytical expertise from fundamental physics to completed operational systems.
The Flash X-Ray (FXR) accelerator produces and accelerates the electron beam which is then converted to X-rays via the X-ray converter target. These X-rays then are used to image dense hydrodynamic events during shot-time in the Containing Firing Facility (CFF).
Model, fabrication and setup, and detonation of a pulsed power experiment—part of the Phoenix series of explosively driven magnetic flux compression generator experiments.
The ETA-II electron beam accelerator, a 5 MeV, 2 kA, 40 ns, 1 Hz (1 pps) accelerator used for accelerator component development and physics studies. ETA-II holds the record for high average power and was operated at 3 kHz, 50-pulse bursts.
The High Average Power Test Stand.
Low power experiments at the Naval Air Warfare Center, China Lake, involve (a) positioning an AH-1S Cobra helicopter on a foam support tower. LLNL's portable time-frequency source and diagnostic trailer was used for monitoring the AH-1S test points via fiber optic connections. (b) Continuous wave coupling measurements over a broad range represent a threat spectrum and include high-frequency-induced current measurements for monitoring the connecting signal lines and cavity coupling measurements. (c) Technicians place sensitive, nonobtrusive RF sensors in the helicopter.

The stainless steel cylinder on the left is the Mag1D nonlinear magnetic pulse compressor. It is comprised of ferromagnetic core material, which largely determines the output pulse length.
As part of LLNL's ground penetrating radar experiments, modeling and simulation was also performed. In this image, the electromagnetic wave is shown propagaing through the aggregated concrete and reflecting off of the rebar structures.
This is the underside of the HERMES road scanning ground penetrating radar showing the phased array.
LLNL's Anechoic chamber is used for a variety of RF testing. Shown here is a broadband antenna undergoing pattern recording.
The effects of electromagnetic energy coupling into circuit simulations is shown with color-coded intensity.
Operation of a dense plasma focus (DPF) Z-pinch during beam-into-plasma experiments: This time-lapsed rendering illustrates the formation of an umbrella-shaped plasma sheath (purple) being accelerated down the length of a cylindrical electrode, eventually collapsing inward on itself to create a tremendously dense region (white). Simultaneously, an ion beam (green) is timed to pass through the device as the plasma collapses in on itself, to measure the acceleration of the beam particles.
