Abstract :
Summary form only given. Plasma potential measurements in electric propulsion systems are necessary for complete performance evaluations. There have been several measurement methods proposed in the past without a clear indication of which method is the most accurate. An investigation was performed to compare a number of these methods. The techniques employed here include two different emissive probe methods and a procedure that involves the analysis of the electron energy distribution function. Near- and far-field measurements were taken in the plumes of a stationary plasma thruster and an anode layer thruster. The techniques employed are explained, and an analysis of the measurements are discussed.
