The physics of electrodeless electric thrusters that use directed plasma to propel spacecraft
without employing electrodes subject to plasma erosion is reviewed. Electrodeless plasma …

Abstract Journal of Physics D: Applied Physics published the first Plasma Roadmap in 2012
consisting of the individual perspectives of 16 leading experts in the various sub-fields of 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 …

The transition from old space to new space along with increasing commercialization has a
major impact on space flight, in general, and on electric propulsion (EP) by ion thrusters, in …

Neutral depletion can significantly affect the steady state of low temperature plasmas.
Processes that lead to neutral depletion and the resulting plasma–neutrals steady state are …

Higher magnetic fields are always favoured in the magnetoplasmadynamic thruster (MPDT)
due to its superior control of the plasma profile and acceleration process. This paper …

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 …

Pre-ionization caused by runaway electrons is an important mechanism for negative
streamer development. The aim of this paper is to investigate the runaway criteria and …

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 …

The performance of an electrodeless thruster operating on water-vapor propellant is
evaluated and compared to noble-gas propellants. Cross-section data for electron …
