Abstract
Non-invasive measurements of electron temperature and density in the near-field plume of a Hall-effect thruster were performed using a laser Thomson scattering diagnostic. Laser measurements were processed using a maximum likelihood estimation method and results were compared to electrostatic double probe measurements. Electron temperature ranged from approximately 1 - 40 eV and density ranged from 1.0 × 1017 m-3 to 1.3 × 1018 m-3 over discharge voltages from 250 to 450 V and mass flow rates of 40 to 80 SCCM. © 2012 by Robert L.
