Thermonuclear ringtones in tokamak plasmas

Key to sustaining fusion plasmas is that they are MHD stable to disruptive mode activity, and other electromagnetic modes do not result in catastrophic performance degradation. The project involves exploiting a generalised MHD code to describe high frequency Compressional Alfven eigenmode activity in high plasma performance international experiments.

Tearing modes in the multi-region relaxed MHD plasma model

The project is to relate the onset of tearing mode instability in MRXMHD to the multi-tearing Delta' formalism of Dewar and Pletzer (developed in an earlier ANU PhD project) and to use this to model recent experimental results in Reversed Field Pinches (RFPs), a class of toroidal fusion devices.

Inclusion of toroidal flow into multiple relaxed region MHD

A new model, multiple relaxed region MHD, has been developed to describe magnetic islands and chaotic fields in toroidal magentic cofinement. This project would extend that model to include toroidal flow.
