    Simulation of magnetic phenomena driven by parallel ion motion (1986)

    Notes: In this paper a one-dimensional Darwin quasineutral hybrid simulation code is used to investigate the large spatial scale (λ∼c/ωpi) low-frequency (ω∼ωci) collisionless evolution of a plasma slug of finite width traveling parallel to an ambient magnetic field in the presence of a uniform background plasma. Such a system may cause excitation of large amplitude magnetosonic waves and mixing of the background and slug ions. Under certain conditions, background ions and slug ions are driven upstream of the interaction region. Particular attention is paid to the width of the plasma slug, thermal effects, the anomalous resistivity, and the relative velocity of the two plasmas.

    Electrostatic ion–ion two-streaming instability in a thermal-barrier cell (1985)

    Notes: Some designs for tandem mirror devices rely on a thermal-barrier cell, a region of depressed potential located between the central cell and the end plugs. This region of depressed potential relies on, to some extent, an ion distribution function that has two peaks in vz (ion velocity parallel to the magnetic axis). Therefore there is a possibility that some ion–ion two-stream modes can be unstable. Using one-dimensional models, the stability of model equilibria to electrostatic ion two-stream modes is considered. The results suggest that for parameters of greatest interest (i.e., for planned experiments), these modes could be stable. Particle simulation techniques are used to examine the nonlinear consequences for those conditions where instability is present.

    Simulation of the ion-beam-driven drift instability in a magnetic trap. II (1985)

    Notes: Recent experiments on the TMX-U device at the Lawrence Livermore National Laboratory have indicated the possibility of a low-frequency (ω(very-much-less-than)Ωci) drift wave being driven unstable by the injection of neutral beams in the thermal barrier region. Nonlocal linear theory is performed for this instability using slab geometry and the electrostatic approximation. Particle simulations are used to verify the linear theory and to recover relevant nonlinear phenomena. Important nonlinear effects include: (1) E×B trapping (2) relaxation of the beam density profiles, and (3) weakly nonlinear electrons (eδφ/Te ≈0.1). These nonlocal simulations are compared with previous simulations of Ref. 1 [Phys. Fluids 28, 2235 (1985)] which used a local approximation for the particle simulations.

    Two-dimensional simulation of high Mach number plasma interactions (1986)

    Notes: In this paper a hybrid particle–fluid simulation code is used to examine the large-scale (λ∼c/ωpi) low-frequency (ω∼ωci) formation and evolution of a collisonless shock in two dimensions where the shock is caused by a plasma slug of finite thickness traveling perpendicular to the ambient magnetic field in the presence of a uniform background plasma. During the evolution of the shock structure, background ions are energized in the perpendicular direction and then isotropized. The isotropization process is associated with the presence of large-amplitude, primarily electromagnetic, waves propagating parallel to the ambient magnetic field that are created by the self-consistent plasma interaction. High Mach number shocks are found to be inherently two-dimensional objects.

    Simulation of the ion-beam-driven drift instability in a magnetic trap. I (1985)

    Notes: Recent experiments on the TMX-U device, at the Lawrence Livermore National Laboratory have indicated the possibility of a drift wave being driven unstable by the injection of neutral beams in the thermal barrier region. A review of linear theory is presented in the local approximation. In addition, particle simulations are used to understand the nonlinear characteristics of this instability. The particle simulations are performed using 1d-3v and 2d-3v electrostatic particle simulation codes. The instability is shown to saturate by beam trapping, nonlinear electron effects, and nonlinear motion parallel to the density gradient. Resonant E×B motion is a significant process for some of the beam particles. This process is closely associated with the trapping of beam ions. Harmonic generation is also observed, as appears in some of the experimental data. Qualitative nonlinear theory is presented in support of the particle simulations.

    One- and two-dimensional simulations of imploding metal shells (1999)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 85 (1999), S. 7626-7634

    Notes: We report results of one- and two-dimensional (2D) magnetohydrodynamic simulations of imploding, cylindrical metal shells. One-dimensional simulations are used to calculate implosion velocities of heavy liners driven by 30 MA currents. Accelerated by the j×B force, 45 g aluminum/tungsten composite liners achieve velocities on the order of 13 km/s. Used to impact a tungsten target, the liner produces shock pressures of approximately 14 Mbar. The first 2D simulations of these liners are also described. These simulations have focused on two problems: (1) the interaction of the liner with the electrically conducting glide planes, and (2) the effect of realistic surface perturbations on the dynamics of the implosion. The former interaction is confined primarily to the region of the contact point between the liner and glide plane, and does not seriously affect the inner liner surface. However a 0.2 μm surface perturbation has a significant effect on the implosion dynamics. © 1999 American Institute of Physics.
