    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (881 KB) | HTML iconHTML

    Pulsed Power Hydrodynamics (PPH) is a new application of low-impedance, pulsed power technology to the study of complex hydrodynamics, instabilities, turbulence, and material properties in a highly precise, controllable environment at the extremes of pressure and material velocity. The Atlas facility, designed and built by Los Alamos, is the world’s first, and only, laboratory pulsed power ... View full abstract»

  • Energy losses in high current density conductors

    Publication Year: 2007, Page(s):937 - 941
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3586 KB) | HTML iconHTML

    The Z accelerator at Sandia National Laboratories has reached currents in excess of 20 MA; and the new ZR accelerator, scheduled to come on line later in 2007, will generate currents greater than 26 MA. These very high currents are delivered to loads with characteristic dimensions of ∼ 1 cm or less. The resulting linear current densities can exceed 5 MA/cm. At these current densities there ...

    Inertial confinement fusion at the National Ignition Facility (NIF) is a grand challenge embraced by the nation. The designs of fusion ignition targets are based primarily on the indirect drive concept in which 351 nm laser light is absorbed by the wall of a cylindrical hohlraum, typically made of Au in current experiments. The hohlraum is an energy trapping container designed to retain as much of... View full abstract»

  • High density high velocity plasma jet interaction

    We studied high density high velocity plasma jets interaction in 3D using PIC simulation. Different merging regimes were observed. It was found that plasma density and collision angle of the jets are crucial parameters which determine the interaction dynamics. Well focused merged plasma jets were obtained for relatively low densities and velocities of jets. High turbulent plasma flows were observe... View full abstract»

    The results of the investigation of the underwater electrical wire explosions using a high power sub-ns generator are reported. The spectroscopic analysis of the emitted radiation has unveiled no evidence for the formation of shunting plasma channel. The latter appears in vacuum and gas wire explosions and causes to the seizure of energy deposition into an exploding wire material. The combination ... View full abstract»

  • Non-thermal atmospheric RF plasma in one-dimensional spherical coordinates

    Publication Year: 2007, Page(s):957 - 960
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (377 KB) | HTML iconHTML

    We present one-dimensional simulations of atmospheric pressure RF-excited plasma with two concentric spherical electrodes and the inner electrode powered. The coupled continuity equations and electron energy equation are solved with Poisson’s equation using the finite element method. A mode transition is observed in the discharge power-voltage curve between 1 mW and 1000 mW. In the low powe... View full abstract»

  • Adiabatic thermal equilibrium for axisymmetic intense beam propagation

    Publication Year: 2007, Page(s):961 - 965
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (818 KB) | HTML iconHTML

    An adiabatic equilibrium is obtained for an intense, axisymmetric charged-particle beam propagating through a periodic solenoidal focusing field. The thermal beam distribution function is constructed. The beam root-meansquare (rms) envelope equation is derived, and the selfconsistent nonuniform density profile is calculated. Other statistical properties such as flow velocity, temperature, total em... View full abstract»

  • Role of plasmas in the operation of a self-magnetically pinched diode

    The self-magnetic pinch diode is being developed as an intense electron beam source for high-power x-ray radiography. The diode is comprised of a ∼1-cm diameter, hollow cathode with a rounded tip from which a high-current electron beam is emitted. The beam self focuses in its own magnetic field as it propagates across a ∼1-cm vacuum gap where it deposits its energy onto a planar high... View full abstract»

  • Influence of dissipation on instability of overlimiting electron beam

    Publication Year: 2007, Page(s):970 - 974
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (325 KB) | HTML iconHTML

    Interaction of overlimiting electron beam with spatially separated plasma in waveguide is investigated. In wide range of system parameters the instability is caused by growing of beam slow wave of negative energy. In this case dissipation in the system leads to a new type of dissipative beam instability with inverse proportional dependence on dissipation. Growth rate of this instability is obtaine...

    Sandia’s Z Refurbishment (ZR) Project formally began in February 2002 to increase the Z Accelerator’s utilization by providing the capability to perform more shots, improve precision and pulse shape variability, and increase delivered current. A project update was provided at the 15th International Pulsed Power Conference in 2005 [1]. The Z facility was shut down in July 2006 for str... View full abstract»

    The Z pulsed power driver [1] at Sandia National Laboratories is used to develop high energy density z-pinch x-ray sources for inertial confinement fusion research and radiation effects testing, and to drive megabar pressures in material samples for equation of state studies. The entire pulsed power system is in the process of being replaced, improving reliability and increasing the energy deliver... View full abstract»
