Interaction of plasma flows with magnetic fields can lead to excitation of flute-like oscillations. These oscillations can also be excited in Z-pinch plasmas. We have developed understanding of nonlinear dynamics of compressible flute mode turbulence

The Z-pinch dynamic hohlraum (ZPDH) is a high-power x-ray source that has been used in a variety of high energy-density experiments including inertial confinement fusion (ICF) studies. The system consists of a tungsten wire-array Z pinch that implode

The dynamics of large- and small-scale plasma structures is investigated in the precursor of 1-MA wire array Z-pinches by laser probing diagnostics. It is found that plasma streams from the wires induce density perturbations in the precursor. Small-s

Recent experiments (laser multiframe shadowgraphy and Faraday rotation diagnostics) with Al imploding wire arrays in the 1-MA "Zebra" accelerator at the Nevada Terawatt Facility have demonstrated that a significant amount of current is going through

Deuterium-filled capsule implosion experiments that employ the dynamic hohlraum are presently being conducted on the Z facility at Sandia National Laboratories. This paper will address the evidence for thermonuclear neutron production in the initial

The pulsed-power driven double-ended vacuum hohlraum allows highly symmetric capsule implosions, aided by the separation of the capsule from the z-pinch and its associated instabilities, spatial variations, and non-thermal spectral components. Experi

Fast ignition using pulsed-power drivers combines the efficient production of X-rays to drive fusion fuel assembly with precise ultraintense laser pulses for fuel ignition. Z-pinches convert electrical energy into thermal X-ray energy with high effic

Pulsed-power machines can deliver large electrical energies to Z-pinches, which efficiently convert this energy into X-rays that can indirectly drive capsule implosions to obtain high-fusion fuel (D-T) densities. Presently, the Z machine generates 1.

The long-range goal of the Z-Pinch IFE program is to produce an economically-attractive power plant using high-yield z-pinch-driven targets (~3GJ) with low rep-rate per chamber (~0.1 Hz). The prese...
