An alternative source for generating atmospheric pressure non-thermal plasmas

This communication presents an alternative source for the generation of non-thermal plasmas at atmospheric pressure. It is based on a very simple electric diagram that generates, on the plasma electrode, an electric field sufficiently high to ionize various gases (helium, argon or even air), which flow at atmospheric pressure. The dc power supply is lower than 10V, the frequency of the electric field is in the range 0.1-1 MHz and the plasma power is less than 1 W. The plasma is generated using only one electrode. It has all the characteristics of non-thermal plasmas.
