Abstract

An experimental study and numerical calculations of the influence of geometric and electrical parameters of ion sources with ionization at atmospheric pressure on the motion of ions from ionization site to an entrance orifice were carried out. The effect of space charge on the current-voltage characteristics of an electrode configuration of the ion source was experimentally shown. The results of numerical calculations of ion motion with allowance for the space charge in a stationary ion flow based on the statistical diffusion simulation model were shown to agree well with the experiment. The possibility of 100% ion transportation from the ionization area to a collector was demonstrated experimentally and numerically.
