Positron emitters are embedded in clouds of dust grains produced by supernova. This project will explore the transport of positrons in dust grains using Monte-Carlo techniques to improve our understanding of positron transport in an astrophysically relevant setting.

The traditional approach transport simulation is to measure cross sections and feed them into a code package. However, some cross sections are very difficult to both measure and calculate. The "inverse swarm problem" seeks to extract these cross sections from transport measruements such as current profiles or annihilation rates.

Positronium is a bound state between an electron and a positron. It is hydrogen-like with a binding energy half that of hydrogen. Positronium has been found to scatter like an electron for the same velocity. Electrons can fragment molecules by temporary attaching leading to fragmentation. This project will explore the fragmentation of molecules in positronium scattering with molecules.

Using the atomic and molecular physics positron beam at the ANU, the student will undertake measurements of positron scattering from simple targets, providing high accuracy data to test recent theoretical calculations.

Although much progress has been made in understand how electrons and positrons move throughout liquids, one cruicial property, V₀, the "background energy" is poorly understood. This project aims to calculate V₀ using an ab initio model.

Low temperature plasmas are being exploited for new medical therapy techniques and in engineering applications in agriculture. This project explores the fundamental behaviour of how electrons penetrate a liquid surface, such as the skin of the body.

This is a multi-faceted project which can be adapted to students at the honours level and above. A number of possibilities exist to perform experiments directed towards improving the use of positrons in medice, mostly focussed on Positron Emission Tomography (PET).

Characterising plasmas is difficult. This project will explore the possibilty of probing a plasma using positrons by building a model and simulating a positron beam incident on a low-temperature plasma.

Plasma agriculture is an innovative field that applies plasma to agriculture processes such as farming, food production, food processing, and food preservation.  In agriculture, plasmas may be used to eradicate all microorganisms; bacterial, fungal and viral particles in fruit and vegetables.

This project aims to develop new plasma processing techniques which can be used to generate complex nanostructured surface morphologies on a range of mateirals. These materials have potential applications in a wide range of areas, including catalysis, high energy-density batteries, and anti-reflection coatings.

Fusion energy promises millions of years of clean energy, but puts extreme stress on materials. This research will resolve scientific issues surrounding plasma-material interactions to guide and facilitate development of future advanced materials for fusion reactors.

Turbulence is known to affect the plasma in toroidal magnetic confinement devices for fusion, and linear magnetic devices. This project involves the use of langmuir probes on both the H-1 and MAGPIE devices for evaluating the total and fluctuation-induced particle flux and address fundamental physics of turbulence in these devices.

This project involves studying the complex plasma-surface interaction region of a fusion-relevant plasma environment through laser-based and spectroscopic techniques.
