High Voltage Pulsed Atmospheric Pressure Helium Plasma Jet
نویسنده
چکیده
Non-equilibrium cold plasma jets generated under atmospheric pressure by means of high voltage pulsed power generator are extended up to a few centimeters long in the surrounding air. The generator is consisting of a negative dc source, a Blumlein-type pulse-forming network (E-PFN), and a dynamic spark gap switch. The plasma jet generated by the device using helium as the operating gas depends on the applied voltage and the gas flow rate. It is found that the plasma jet width and the radiant intensity depend on the discharge current.
