The method of experimentation is used to research the ionization efficiency in dielectric barrier discharge ion source in condition of gas’s different flux.The object of this experiment is the standard mixtures gases of ethanol in nitrogen.Research findings show that the ionization efficiency of this ion source is diminished with when the gas’s flux is increased.For example
when the flux is 60 L/h
the ionization efficiency is as high as 33 %
but ionization efficiency is decreased tempestuously with the increasing of flux.Once the flux overstep about 160 L/h
the decreasing trend of the ionization efficiency gets smaller.When the flux reaches the maximum(400 L/h) the ionization efficiency gets the minimum(about 3.5 %).
