Ion Cyclotron Resonance Heating Induced Transport in Stellarators and Other Asymmetric Toroids
A Monte Carlo simulation is developed to model minority ion transport and fundamental ion cyclotron resonance heating (ICRH) in asymmetric magnetic field geometries. A discrete event model is used to superimpose resonance heated nonadiabatic changes in an ion's magnetic moment on a Coulomb …

Modeling enhanced impurity sputtering due to rf sheaths in front of ICRH actuators
One of the main concerns over using the Ion Cyclotron Resonance Heating (ICRH) is the enhanced impurity sputtering phenomenon due to the emergence of RF sheaths near the Faraday Screen of the ICRH antenna. Here we present a semi-analytical fluid plasma model able to capture the enhanced sputtering …

Theoretical studies of the VASIMR plasma propulsion concept
This dissertation was motivated 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 …
