Advanced materials for space propulsion: satellites and cubesats. Poorly controlled interactions between plasmas and surfaces often mean loss of process efficiency and surface degradation over time. For Hall thrusters, a type of engine used to move satellites in space, this means increased fuel consumption and shorter useful life.

Poorly controlled interactions between plasmas and surfaces often mean loss of process efficiency and surface degradation over time. For Hall thrusters, a type of engine used to move satellites in space, this means increased fuel consumption and shorter useful life. Through modelling and experiment, this project will show how intelligent selection of advanced materials and plasma parameters can minimise surface wear, enable in situ material repair to extend device lifetime, and modulate plasma properties to increase thruster efficiency for a given task. These benefits enable reliable propulsion platforms for massive communication and observation satellite networks and deep space exploration.Read moreRead less
Towards a steady-state fusion reactor: understanding and controlling eruptive instabilities in tokamaks. The lifetime of future fusion reactors may be severely compromised by periodic releases of internal energy which can damage the reactor walls. In an international research effort that is based on unique Australian optical technologies, the project aims to resolve some of the key issues that should allow these instabilities to be suppressed.

These dynamics are important to nuclear reactor materials and to developing new nanotechnology materials for high energy density lithium-ion battery anodes and water splitting catalysts. Through model and experiment, this project expects to generate new knowledge of processes that drive sub-surface nano-bubble formation and surface nanowire growth in materials exposed to helium particles. This project will result in improved understanding of material degradation during nuclear reactor operation and will make a new contribution to high-value manufacturing capabilities for next generation energy systems.Read moreRead less

Summary
A diagnostics platform for advanced plasma-chemical analysis. A wide range of production processes involve the use of plasmas to modify materials, but they are not well understood. This project will give Australian researchers the tools to look inside plasma processes and fully characterise them for the first time, unlocking new knowledge and providing new insight into the plasma processing environment.
Understanding molecular negative ion production for use in pathology. The project aims to increase the yield of molecular negative ion sources by improving our understanding of the formation of ion beams from plasma sources and expand our knowledge of molecular negative ion generation in plasma environments leading to brighter ion beams. For example, understanding cancer requires cellular level tools to map how cells are changing. These maps are made using ion beams which are scanned across cell ....Understanding molecular negative ion production for use in pathology. The project aims to increase the yield of molecular negative ion sources by improving our understanding of the formation of ion beams from plasma sources and expand our knowledge of molecular negative ion generation in plasma environments leading to brighter ion beams. For example, understanding cancer requires cellular level tools to map how cells are changing. These maps are made using ion beams which are scanned across cells to remove material that is analysed at the atomic and molecular level. Ion beams are produced from plasma sources, but much of their operation is not understood. Such improved ion beams are expected to enable inexpensive and fast cellular level pathology at even small hospitals to tackle cancer for society’s benefit.Read moreRead less

New technology developed by Australia, Sweden and the United States will be applied to major questions about the application of relativistic quantum mechanics to atomic structure and dynamics and spectroscopy, especially including critical issues in quantum electro-dynamics for atomic physics and applications. Discrepancies in quantum electro-dynamics have dominated international debate for decades, with claimed explanations annually failing to reveal the cause. Also a pattern of discrepancies has been seen at X-ray energies in first row metal atoms, with a similar sign and magnitude. A combined experimental an theoretical investigation will aim to reveal new light on these anomalies and serve to develop our understanding of the universe.Read moreRead less

This project aims to apply a static plasma modelling approach to linear modes of vibration and nonlinear explosive events in toroidally confined fusion plasma experiments and stellar atmospheres. The long-term survival of advanced civilisation depends on the development of reliable and ecologically sustainable energy sources. One of the most promising approaches for baseload electrical power is magnetic confinement fusion: harnessing, in a magnetic field, the nuclear reactions that power stars. This project will develop powerful new ways of modelling strong plasma instabilities in magnetised plasmas. Learning how to avoid these would remove a key barrier to fusion power.Read moreRead less
