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 Gift Cards imaging system was one nanosecond.A unique three-stage process, including a fast ignition at the leading edge of the pulse, quenching at the plateau of the pulse, and self re-ignition at the trailing edge of the Leather Flip Wallet Phone Case 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 under high reduced electric field conditions was discussed.
