Theoretical studies of the VASIMR plasma propulsion concept
… by the Variable Specific Impulse Magnetoplasma Rocket (VASIMR) project. The VASIMR device has a magnetic mirror configuration and consists of three main components: a low energy helicon plasma source, which creates cold plasma via rf-discharge; an ion cyclotron-resonance heating (ICRH) …

Comparative simulations of conceptual ion extractors for use in asymmetric inertial electrostatic confinement
Many deep space propulsion missions currently use ballistic trajectories to reach their destinations. To reduce the times of flight, electric or plasma based propulsion systems are used. While Hall Effect thrusters are the general standard for plasma propulsion, new technologies can enable shorter …

Plasma flow and acceleration in the magnetic mirror and nozzle geometries
… investigates key physics governing transonic plasma flow within converging-diverging magnetic field (magnetic nozzle) configurations as used in fusion open mirror systems and plasma propulsion applications. In such configurations, plasma is accelerated from subsonic to supersonic velocities …
