TURBULENT EDDIES IN HIGH-DENSITY-SPARK CHANNELS IN HELIUM.

Abstract

Turbulent eddies in high-pressure microsecond-spark channels in helium were photographed by means of a 20-nsec Kerr-cell shutter. Current densities exceeded 1,000,000 A/sq. cm. It was shown that turbulences are initiated from plasma jets originating at the electrodes. The cathode jet is explained by Compton's accommodation theory which was extended by Haynes. The observed anode shock wave appears to be the result of a dynamic magnetic pinch. (Author)
