Determination of Electron Density in Atmospheric Pressure Radio Frequency Dielectric Barrier Discharges by Stark Broadening
The use of high frequency power to generate plasma at atmospheric pressure is a relatively new development. An apparatus of atmospheric pressure radio frequency dielectric barrier discharge was constructed. Plasma emission based measurement of electron density in discharge columns from Stark broadening Ar is discribed. The spacial profile of electron density was studied. In the middle of the discharge column, as the input power increases from 138 to 248 W, the electron density rises from 4.038×1021 m-3 to 4.75×1021 m-3.
