Control of Plasma jet produced by pulsed power

Non-thermal plasmas have been generated using repetitively operated pulsed power generators, demonstrating the technology´s potential in creating discharges relatively easily at atmospheric pressure. Control of plasma jets at atmospheric pressure facilitates a wide range of applications in material modification, medicine, and energy. This paper investigates five factors which affect plasma length under dielectric barrier discharge: applied voltage, current, repetition rate, the size of the coaxial configuration, and gas flow velocity. Helium gas was used for easy observance of light emission.
