Abstract

An atmospheric pressure nitrogen plasma jet sustained by a repetitive pulsed DC power source is studied The afterglow characteristics of this plasma jet are studied by an optical emission spectrometer and thermocouples The effects of the process parameters namely the applied voltage and the gas flow rate on the plasma characteristics are investigated It is shown that the plasma reactivity is controlled by the power deposition to the plasma as well as the decay process of the reactive species upon formation The reactivity increases with the increase in the applied voltage and with the decrease in the gas flow rate The jet temperature is primarily controlled by the power density and it increases with the increase in the applied voltage and with the decrease in the gas flow rate These observations suggest that the plasma reactivity and the jet temperature of this plasma jet can be nearly independently controlledThis work was supported by National Science Council NSC 982221E002047 and NSC 983114E002012 The authors are grateful to Prof K C Leou at National Tsing Hua University Prof T C Wei at Chung Yuan Christian University and Prof J S Wu at National Chiao Tung University for fruitful discussions
