Simulating a pulsed power-driven plasma with ideal MHD
A. Beresnyak, A. L. Velikovich, J. L. Giuliani +4
We describe a simple practical numerical method for simulating plasma driven within a vacuum chamber by a pulsed power generator. Typically, in this type of simulation, the vacuum…
Perpendicular subcritical shock structure in a collisional plasma experiment
D. R. Russell, G. C. Burdiak, J. J. Carroll-Nellenback +13
We present a study of perpendicular subcritical shocks in a collisional laboratory plasma. Shocks are produced by placing obstacles into the super-magnetosonic outflow from an inve…
Stable and unstable supersonic stagnation of an axisymmetric rotating magnetized plasma
Andrey Beresnyak, Alexander L. Velikovich, John L. Giuliani +1
The Naval Research Laboratory "Mag Noh problem", described in this paper, is a self-similar magnetized implosion flow, which contains a fast MHD outward propagating shock of consta…
D'yakov-Kontorovich instability of expanding shock waves
César Huete, Alexander L. Velikovich
In the range of , where is the D'yakov-Kontorovich parameter, is its critical value corresponding to the onset of the spontaneous acoustic emission, and $M…
Magnetic Field Transport in Propagating Thermonuclear Burn
B. Appelbe, A. L. Velikovich, M. Sherlock +4
High energy gain in inertial fusion schemes requires the propagation of a thermonuclear burn wave from hot to cold fuel. We consider the problem of burn propagation when a magnetic…
Stability of stagnation via an expanding accretion shock wave
A. L. Velikovich, M. Murakami, B. D. Taylor +3
Stagnation of a cold plasma streaming to the center or axis of symmetry via an expanding accretion shock wave is ubiquitous in inertial confinement fusion (ICF) and high-energy-den…
Observed transition from Richtmyer-Meshkov jet formation through feedout oscillations to Rayleigh-Taylor instability in a laser target
Y. Aglitskiy, M. Karasik, A. L. Velikovich +8
Experimental study of hydrodynamic perturbation evolution triggered by a laser-driven shock wave breakout at the free rippled rear surface of a plastic target is reported. At sub-m…
