Hydromagnetic Rayleigh–Taylor instability in high-velocity gas-puff implosions
Autor: Melissa Douglas, Thomas W. Hussey, R. B. Spielman, R. E. Peterkin, Norman F. Roderick, C. Deeney
Publikováno v: Physics of Plasmas. 5:1477-1484
Experiments using the Saturn pulsed power generator have produced high-velocity z-pinch plasma implosions with velocities over 100 cm/μs using both annular and uniform-fill gas injection initial conditions. Both types of implosion show evidence of t

Secondary electron emission at anode, cathode, and floating plasma‐facing surfaces
Autor: R. E. Peterkin, C. A. Ordonez
Publikováno v: Journal of Applied Physics. 79:2270-2274
The secondary electron emission coefficient is evaluated for electron impact on anode, cathode, and electrically floating plasma‐facing surfaces. Two energy and angle distribution functions for electron impact on a plasma‐facing surface are deriv

Research on the formation of a hot hydrogen working fluid, which may be used in multiple concentric solid‐density liner implosions, is reported. In such implosions, an axisymmetric outer liner is driven by a multi‐megamp axial discharge, and a co

Experiments with coaxial plasma guns at currents in excess of ten megamperes have resulted in the production of high‐voltage pulses (0.5 MV) and hard x radiation (10–200 keV). The x‐radiation pulse occurs substantially after the high‐voltage

Virtual cathode formations in nested-well configurations
Autor: R. E. Peterkin, C. A. Ordonez, K. F. Stephens
Publikováno v: AIP Conference Proceedings.
Complete transmission of an electron beam through a cavity is not possible if the current exceeds the space-charge limited current. The formation of a virtual cathode reflects some of the beam electrons and reduces the current transmitted through the

Boundary conditions for use in plasma simulations
Autor: R. E. Peterkin, K. F. Stephens, C. A. Ordonez
Publikováno v: IEEE Conference Record - Abstracts. 1997 IEEE International Conference on Plasma Science.
Summary form only given, as follows. Boundary conditions are presented for use in magnetohydrodynamic, particle-in-cell, and multi-fluid computer programs. The boundary conditions consist of velocity moments for three plasma species near a plasma-fac
