The performance of large inert-gas thrusters is predicted based on present knowledge of ion optics performance and discharge chamber operation. Calculated performance data are given for argon and xenon propellants. The effect of varying propellant utilization and thruster diameter is discussed and the optimum choice of beam diameter for very large systems is indicated for low, intermediate, and high specific impulses. Optimum discharge chamber depths are also specified. Although detailed design considerations may modify the predictions, the general trends indicated should still be useful for directing future technology efforts and evaluating mission studies involving large thrusters.
