Temporally resolved imaging on quenching and re-ignition of nanosecond underwater discharge
This paper presents the temporally resolved images of plasma discharge in de-ionized water.The discharge was produced by high voltage pulses with 0.3 ns rise time and 10 ns duration.The temporal resolution of the Gift Cards imaging system was one nanosecond.A unique three-stage process, including a fast ignition at the leading edge of the pulse, qu
