Temporally resolved imaging on quenching and re-ignition of nanosecond underwater discharge

Blog Article

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 imaging system was one nanosecond.A unique three-stage process, including a fast ignition at the leading edge Waist of the pulse, quenching at the plateau of the pulse, and self re-ignition at the trailing edge of the pulse, was observed in a single pulse cycle.The maximum measured propagation velocity of the plasma discharge was about 1000 km/s.

The possibility of direct ionization in water Slide Duel Fuel Range under high reduced electric field conditions was discussed.
