Paper Abstract

When a condensor is discharged between two electrodes in a thin Layer of liquid, a light flash is produced. The light emission is detected with a fast silicon detector filtered for red, green and blue light. The spark discharge and the shock waves in the liquid layer are photographed with X-ray flashes. The energy transfer to the gas plasma is much higher for a second or third discharge which follows the first discharge after some microseconds, if it is a discharge into the spark induced gas plasma and not in the liquid. The expansion of the gas plasma has been studied therefore in detail. A simple arrangement of two condensors and a coil makes it possible to produce flash sequences. The spark was produced in different organic liquids and H2O.
