The Quad Confinement Thruster is a DC magnetized plasma propulsion system invented and developed within the Surrey Space Centre (University of Surrey). The QCT contains a square discharge channel with the anode located at the closed, upstream end. An external hollow cathode neutralizer provides primary electrons for triggering the ionization process (via electron-neutral collisions) and...

Understanding the expansion of the plasma plume produced by an electric propulsion system into vacuum is a fundamental problem for predicting the thruster performance, improving thruster design, and flagging any potential spacecraft integration problems due to plasma-surface interaction.
This talk covers, firstly, the key challenges of modelling a magnetized plasma jet in a divergent magnetic...

The development plan of CIRA Electric Propulsion Program financed by PRORA, called IMP-EP1, is structured in three main lines and will develop according to:
I. design and realization of the facilities (MSVC, LSVC) including the improvement of test definition and competences;
II. development and improvement of basic and advanced diagnostics methodologies;
III. development of design...

Hollow cathodes are sources of electrons to ionize the propellant and neutralize the ion beam exhausted by ion and Hall effect thrusters. A complete understanding of the operation of hollow cathodes is hindered by the complexity of their driving physical processes along with the difficult plasma diagnostics due to the small size (typically a few millimeters in diameter) and high operating...
