Conceptual modeling of the multiaperture electrode system of a 5-cm-diam ring cusp ion thruster intended for producing a 1 mN thrust is described. A mathematical treatment of the ion extraction from the plasma has been developed to provide a method for calculating both the shape and potential of the plasma-emitting surface. The ion optics of the electrode system have been examined using a numerical code to evaluate the ion beam divergence. Close agreement is achieved between the predictions of the conceptual modeling presented here and published experimental results. © 1996 American Institute of Physics.
