Abstract:
A high PRF plasma gun including:a center electrode;an outer electrode substantially coaxial with said center electrode, a coaxial column being formed between said electrodes, which column has a closed base send and an open exit end;an inlet mechanism for introducing a selected gas into said column;a plasma initiator at the base end of said column;a solid state simulated high voltage RF source selectively connected to drive said plasma initiator, said RF source operating at a frequency in the range of 10 MHz to 1000 MHz; anda solid state, high repetition rate pulsed driver operable on plasma initiation at the base of said column for delivering a high voltage pulse across said electrodes, the plasma expanding from the base end of the column and off the exit end thereof.
