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.

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).

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.

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.

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.

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.

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.

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

Nuclear fusion is a promising technology for solving the world’s energy crisis while drastically reducing pollution and avoiding the creation of nuclear waste, a major issue for nuclear fission. However, there are many scientific and technical challenges to be overcome before this technology can be used for large-scale energy generation. One of the problems that need to be solved is the tolerance of the diverter walls to the high temperatures and He implantation – conditions that are prevalent inside the fusion reactors.

Plasma–liquid interactions are an important topic in the field of plasma science and technology. The interaction of non-equilibrium plasmas with a liquid have many important applications ranging from environmental remediation to material science and health care.
