A triggered spark-gap switch for high-repetition rate high-voltage pulse generation

A triggered spark-gap switch together with a LCR trigger circuit has been developed in order to produce high levels of pulsed corona plasma at high-repetition rate and with a long lifetime. The spark-gap switch is flushed in air with a gas flow rate of up to 100 m3/h. Experiments are carried out up to 10 kW average output power, 12 J/pulse, and 900 pps (pulses per second)
