This contribution presents a short review of electric propulsion (EP) technologies for
satellites and spacecraft. Electric thrusters, also termed ion or plasma thrusters, deliver a low …

Unequal areas of the powered and grounded electrodes in single-frequency capacitively
coupled plasmas (CCPs) are well-known to generate a DC self-bias voltage and an …

In this Tutorial, surface and double charge exchange negative ion sources for producing
negative ion beams of different ion species will be described. The need for negative ions as …

In order to ensure the space charge compensation of the plume, conventional ion thrusters
need an additional neutralizer to release electrons. When a radio-frequency (RF) voltage is …

This paper deals with a study of H−/D− negative ion surface production on diamond in low
pressure H 2/D 2 plasmas. A sample placed in the plasma is negatively biased with respect …

Electrons neutralizing the ion beam from a gridded ion source are typically provided by an
external cathode. This cathode emits a continuous current that ensures quasi-neutrality of …

Ce travail de thèse porte sur le propulseur électrique de type ECR (résonance cyclotron
électronique) développé à l'ONERA. Ce propulseur quasi-neutre, qui utilise une tuyère …

This work focuses on the understanding of the production mechanism of negative-ions on
surface in low pressure plasmas of H 2/D 2. The negative ions are produced on a Highly …

Oscillations within the plume of a Helicon Plasma Thruster are experimentally characterized.
An array of electrically-floating probes is used to resolve the power spectral density, the …

This paper reports on the design, the building, the calibration, and the use of a compact E× B
probe that acts as a velocity filter or a mass filter for ion species. A series of measurements …
