Title: Observation of a spark channel generated in water with shock wave assistance in plate-to-plate electrode configuration

When a high voltage pulse with an amplitude of 30‚ÄČkV is applied to a pair of disk electrodes at a time when a shock wave is passing between them, an electrical spark is generated. The dynamic changes in the spark morphology are studied here using a high-speed framing camera. The primary result of this work is the provision of experimental evidence of plasma instability that was observed in the channel of the electric spark.
