Experimental Study of a Minitype Atmospheric Non-equilibrium Plasma Source

摘要

A mini-type of plasma source was studied experimentally.The results showed that the plasma density,which was generated by an atmospheric non-equilibrium plasma source,rises with the increase in driving electric-field and the momentum of gas particles.For a driving electric- field of 56 kV/cm and a gas particles' momentum of 10~9×10^(-22)g·m/s,the ion density can exceed 10^(10)/cm^3 while the effective volume of the plasma source is only 2.5 cm^2.This study may help develop a method to generate a minitype plasma source with low energy consumption but high ion concentration.This source can be used in chemical industry,environmental engineering and military applications.
