Atmospheric Plasma Jet Relay Driven by a 40-kHz Power Supply and Its Representative Characteristics

One type of atmospheric plasma jet relay driven by a 40-kHz power supply and its representative characteristics have been proposed in this paper. The plasma jet relay succeeds in the same gas stem or inside another guided dielectric tube. The first plasma jet can be capable of dividing into many small plasma jets at the end of metal wires and the filial generations can easily merge together to form longer volume discharges. The experiment indicates that the filamentary discharge starts from the formation of one snake-like discharge passage first and the followed snakes give birth from the previous snake discharge body. Taking into account the advantage of easily production methods and available to extend its discharge volume, the proposed plasma jet relay device can be modulated for many potential applications.
