Abstract (en)

[origin: WO0058989A1] A high pulse repetition frequency (PRF) plasma gun is provided, which gun inlets (74) a selected propellant gas into a column (16) formed between a center electrode (12) and a coaxial outer electrode (14), utilizes a solid state high repetition rate pulse driver (130) to provide a voltage across the electrodes (12, 14) and provides a plasma initiator (82) at the base of the column (16), which is normally operative when the driver is fully charged. For preferred embodiments, the initiator (82) includes a solid state simulated RF driver (130), the output is applied to the electrodes (91) affixed in an insulator (72) and producing a high voltage field at a surface of the insulator (72) which forms part of the base end of the column (16).
