Atmospheric Pressure Helium Plasma Jet Composedof Two Electrodes

Two-electrode plasma jet system consisting of a glass tube with only outer and one floating innerelectrodes was developed and employed for sterilization of root channel of teeth. The experimentalset up is based on very simple and low cost electric components that generate electrical fieldsufficiently high at the electrodes to ionize various gases, which flow at atmospheric pressure. Thehigh d.c power supply is 8.2kV peak to peak, the frequency of the electrical field is 153 kHz, and theplasma power less than 72W. The plasma is generated using two electrode. In the present work thevoltage and current discharge waveform are measured. The temperature of the working He gas atdifferent gas flow and distances from the plasma electrode tip was recorded.
