Description	Content Atmospheric pressure glow discharges (APGD) based on dielectric barrier discharge (DBD) offer the prospect of a future basic technolo8 for low-tcmperature proccssing of gaseous and solid materials without the use of a vacuum chaiuber 1}. DBD based atmospheric preveure plasma jets (APPJ’s) have wide range of potential applications such as thin film deposition \|2J, sterilization \|3], surface modification 4-5) , and etching \|GJ . Important properties of this type of plasma are that it operates near room temperature, allows treatment of irregular surfaces and has a small penetration depth 7) . A floating helix electrode configuration 8] was implemented for generation of atmospheric pressure DBD based cold plasma jet using Ar/He gas. In this paper, floating helix electrode configuration has been used to genei-ate atmospheric pressure DBD based cold plasma jet using a mixture of argon and nitrogen gas. It was subjected to a range of supply frequencies (10-25 kHz) and supply voltage (Ò.5-9 kV). The current-voltage characteristics have been analyzerl. Further inore, coneuined power has been estimated at different applied combinations (supply trequency & voltage) for optimum power consumption at maximum jet length.
