SUMMARY OF ELECTRICAL PROPULSION DIAGNOSTIC INSTRUMENTATION

Abstract

This report summarizes the instrumentation development effort that was initiated at the Arnold Engineering Development Center to effect plasma diagnostics during the long-term testing of electrical propulsion systems. Two different ion beam sources were instrumented to obtain the basic properties of the plasma, such as the electron temperature, electron and ion densities, and the space charge potentials. The basic in strumentation required to effect preliminary diagnostics are the ''plasma eater,'' the posi tive ion probe, the Langmuir double probe, the Faraday cup, and the emissive probe. With these devices, it is possible to obtain both integral and differential measurements of the beam characteristics. Analysis of the data is also included.
