A study of ignitor plug operation in a one-millipound pulsed plasma thruster has been performed. Inductive, rather than resistive coupling of the ignitor plug cathode to the thruster cathode electrode has been shown to significantly reduce a carbonaceous deposit buildup on the plug face. A reduction in plug deposition was also demonstrated by the use of a high current, short pulse length, plug trigger circuit.
