CURRENT SHEATH DYNAMICS AND MAGNETOSONIC OSCILLATIONS IN MAGNETOPLASMAS.
Abstract
The electrical breakdown, current sheath formation, and acceleration of current sheaths in deuterium, hydrogen, and argon plasmas are investigated analytically and experimentally. A system of partial differential equations is written from the Maxwell's electromagnetic field equations and plasma equations to describe the current density, resistivity, electron temperature, ion temperature, and degree of ionization as functions of position and time. The plasma equations include: an energy balance equation, an equation relating resistivity to collisions, and ionization equation, and an energy transfer equation. The resulting set of partial differential equations is coded for electronic digital computation on The University of Texas' Control Data Corporation 1604 high speed, electronic digital computer using finite difference techniques. Theoretical results are obtained for initial deuterium gas pressures of 1 micron, 100 microns, and 1 mm Hg.
