This paper presents the design and construction
of non-thermal plasma jet device which was built in
plasma phys. Dept., NRC, AEA, Egypt with a plasma
application group. This design will be useful to initiate
research in different fields such as low temperature plasma,
polymer and biomedical applications. The experimental
operation of this device is conducted with power supply of
(10 kV, 30 mA, and 20 kHz). The discharge process takes
place by using Air as input gas with different flow rates.
The experimental results showed that the maximum plasma
jet length of 7 mm is detected at air flow rate of 12 L/min.
The electrical characteristics of discharge at different flow
rates of Air such as discharge voltage, current, mean
power, power efficiency, and energy have been studied by
using potential dividers and Lissajous figure techniques.
The results of plasma jet temperature along the jet length
showed that the jet plasma has approximately a room
temperature at the end of jet column. |
