Some Techniques for Diagnostics of the Cold Plasma Jet Generated on the Base of the Atmospheric-Pressure Microwave Discharge

The atmospheric-pressure cold plasma jet that is a flowing afterglow of the interelectrode microwave discharge in Ar was investigated using various diagnostic techniques. Waveguide-type 2.45-GHz-plasmatron with the external 6-rod-electrode plasma torch was used as the cold plasma source. High-speed...

Zusammenfassung:	The atmospheric-pressure cold plasma jet that is a flowing afterglow of the interelectrode microwave discharge in Ar was investigated using various diagnostic techniques. Waveguide-type 2.45-GHz-plasmatron with the external 6-rod-electrode plasma torch was used as the cold plasma source. High-speed shadowgraphy was used to obtain spatio-temporal structure of the cold plasma jet. The periodic character of plasma generation was studied using electric probe floating potential measurements with an oscilloscope.
