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 …

There are a number of pressing problems mankind is facing today that could, at least in part,
be resolved by space systems. These include capabilities for fast and far-reaching …

This topical review gathers the last updates concerning caesium-free negative ion sources
presented during the 63 rd Course of the International school of Quantum Electronics of the …

Ion optics are crucial components of ion thrusters and the study of the different ion extraction
solutions used since the beginning of the electric propulsion era is essential to understand …

The sheath formation mechanism is modeled in a four-component collisional
electronegative warm plasma considering the behavior of positive ions by fluid equations …

This paper compares two methods to analyze Langmuir probe data obtained in
electronegative plasmas. The techniques are developed to allow investigations in plasmas …

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 …

The saturation current ratio (SCR) method is considered to be one of the simplest methods
to determine plasma electronegativity in electronegative discharges using a Langmuir probe …

A collisional electropositive plasma having two-temperature (hot and cold) electrons with
non-extensive distribution and warm ions is investigated for the sheath structure by taking …
