Abstract

We are developing a resonance-probe plasma diagnostic that uses a microwave network analyzer for use in electric-propulsion research. To show the feasibility of our resonance-probe implementation, we have measured plasma densities in the plume of the 5-kW-class P5 Hall-effect thruster and compared them to measurements made with a Langmuir probe. Our preliminary work in this area indicates that the resonance-probe technique shows considerable promise. The resonance-probe technique should prove to be a useful tool to support electric-propulsion research since it able to provide high temporal-resolution electron density measurements.
