Abstract

In the present experiment, two current driven turbulent regimes have been studied, characterized by widely differing electrical fields, E, and transient times, t, however such that the products E x t are of comparable magnitude. The first case of turbulent plasma heating occurs by discharging a slow, low field capacitor bank (C-1: <or= 1 mF; <or=5kV) connected to the iron core transformer (0.25 Vs). The pulse edge of this discharge can be typified by E-1m <or= 35V per metre; tau-1 = 1,5x10**-3s; i-1 <or= 2x10**7 A/s. The other case is that of the superposition of one or more time spaced fast high voltage current pulses on top of the current plateau, usually at t approximately equal 8 ms. The pulses originate from a high voltage capacitor bank (<or=40 kV; 25 muF) which is connected to a thick copper shell tightly surrounding the inconel liner. Pulse characteristics are: E-m <or= 1.6 kV/m, tau approximately equal 3.5x10**-6 s. Up to four separate high voltage pulses can be given by the high voltage banks; the results of only two pulses are studied.
