Time-Resolved Measurements of Plasma Properties Using Electrostatic Probes in the Cross-Field Discharge of a Hall Effect Thruster



Time-resolved measurements of the plasma parameters are performed in the plume of a cross-field discharge. The plasma potential is measured with a cylindrical Langmuir probe and an emissive probe. The electron temperature and density are measured with a cylindrical Langmuir probe. The cross-field discharge is maintained in a harmonic oscillation regime to guarantee reproducible conditions for all measurements (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
