OPERATION OF A COAXIAL PLASMA ACCELERATOR
The operation of an electrode-type coaxial plasma accelerator, with a large ratio of outer conductor radius to inner conductor radius, was experimentally investigated, and the results indicate that none of the usual models, slug, snowplow, andd shock, correspond with the results. The velocities attained were in all cases considerably lower than predicted from the actual currents. H, He, Ar, and N were used, both by injection into the accelerator through a fast-acting valve and as a uniform initial gas distribution. Results of current-front position vs time are presented as functions of the various parameters. The shape of the leading surface of the current front was measured with probes, and the luminous plasma was photographed. The current distribution in the front was determined from magnetic probe measurements. (Dissertation Abstr.)
