Abstract

The effect of magnetic field configuration on thrust performance in a 30 W class miniature microwave discharge ion engine was investigated with the objective of improving its thrust performance. The ion beam current with various magnitude of magnetic field was measured, since magnetic confinement and microwave - plasma coupling could be affected by the magnetic field configuration. The ion beam current is increased with the increase in the number of magnets and there is an optimum magnitude of magnetic field. The thrust performance of the miniature microwave discharge ion engine, propellant utilization, and ion beam production cost were 0.67 and 660 W/A, respectively at mass flow rate =0.02 mg/s, and incident microwave power= 8 W.
