Constraining toroidal equilibria to accretion disc observations

In this project we would compare the construction of accretion disc and magnetic configuration Grad-Shafranov problems, and apply a recently developed toroidal magnetic confinement equilibrium code to model an accretion disc. A focus of the project will be constraining free functions to observational data.

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.

Shocks transitions in nonuniform magnetic fields

Recent development of a flowing MHD model for the rotating, collisional column of MAGPIE plasmas discovered the intriguing prediction of opposite axial acceleration of the plasma ions in the subsonic and supersonic regimes. This project would examine the regime above, below, and through the shock.

Lorentz forces in a tokamak

In this project we will examine the forces generated in superconductoring magnetics, and scope the forces generated during a disruption.

The principles and design of a plasma wakefield accelerator

In this project the principles and design of a plasma wakefield accelerator will be reviewed, and the opportunities for a low-cost wakefield accelerator explored.

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.

Modelling a solar fare by MRXMHD

In this project, we apply multiple-region relaxed MHD model, designed to describe the fractal fix of chaotic field lines, magentic islands, and flux surfaces in toroidal magnetic confinement, to describe a solar flare.

Electric field structure of Energetic Geodesic Acoustic Modes (EGAMs)

The project aims to add particle orbit effects to an ANU developed theory for solving the electric field structure of Energetic Geodesic Acoustic Modes (EGAMs). EGAMs are unstable electrostatic oscillations in tokamak plasmas that are harmful to plasma confinements. The project involves analytic components as well as code developments.

Orbit topologies and wave-particle resonance in fusion plasmas

In this project the wave-particle resonance condition will be computed for a range of precomputed particle orbits (and orbit populations), which initially were computed for transport studies. An estimate of wave-drive due to spatial gradients will be afforded using wave functions from an ideal MHD stability analysis and orbit population information, and compared to diagnostics.

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.
