Exploiting new breakthroughs in understanding nuclear fission. This project aims to characterise and quantify the quantum energy levels crucial in determining the mass and energy distributions of nuclear fission products, which recent results show are far from understood.

This project aims to characterise and quantify the quantum energy levels crucial in determining the mass and energy distributions of nuclear fission products, which recent results show are far from understood. Combining new techniques and concepts, distributions will be measured down to the fission barrier energies, maximising sensitivity to quantum effects. The project exploits newly enhanced Australian accelerator infrastructure, world-best detector capabilities, and the latest findings in reactions of light cluster nuclei.

Developing a complete understanding of nuclear fission. This project aims to develop a reliable predictive model of nuclear fission. Nuclear fission is an important process in fundamental physics and technologies spanning energy, medicine and materials science. It was recently found that fission still holds many secrets, since existing models fail to describe new fission measurements for nuclei lighter than the well-known uranium region. This project plans to exploit world-leading Australian res ....Developing a complete understanding of nuclear fission. This project aims to develop a reliable predictive model of nuclear fission. Nuclear fission is an important process in fundamental physics and technologies spanning energy, medicine and materials science. It was recently found that fission still holds many secrets, since existing models fail to describe new fission measurements for nuclei lighter than the well-known uranium region. This project plans to exploit world-leading Australian research equipment to map out unknown fission characteristics in large regions of the nuclear chart, providing a complete microscopic understanding of nuclear fission. This is designed to lead to the first predictive model applicable to the entire nuclear chart, including nuclei of astrophysical importance.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
Anisotropy and flow in fast-particle dominated and burning tokamak plasmas: stability of ITER and the coming demonstration fusion power plant. This project will identify how beam injected and fusion born alphas affect the magnetic ?eld and excite wave modes in spherical tokamaks, where these particles have the most impact. Understanding these effects is critical to long pulse operation of high performance tokamaks with burning plasmas. In the UK spherical tokamak MAST for instance, fast ion driv ....Anisotropy and flow in fast-particle dominated and burning tokamak plasmas: stability of ITER and the coming demonstration fusion power plant. This project will identify how beam injected and fusion born alphas affect the magnetic ?eld and excite wave modes in spherical tokamaks, where these particles have the most impact. Understanding these effects is critical to long pulse operation of high performance tokamaks with burning plasmas. In the UK spherical tokamak MAST for instance, fast ion driven bursty “chirping modes” and “?shbone” modes evolve into "long-lived" modes damaging plasma performance. This project will resolve the physics of the seed fast ion driven mode, its linear threshold and fully nonlinear evolution. Wider outcomes include scoping the impact of beams and alphas in next step burning plasma experiments, such as a nuclear facility for materials development, ITER, and a fusion power plant.Read moreRead less
Emergence and control of self-organisation in fusion plasmas: through the International Thermonuclear Experimental Reactor (ITER) and beyond. Fusion is a carbon free technology, which promises millions of years of base-load power. The promise has led to massive support for the proof-of-principle experiment, ITER. A challenge facing ITER is minimising edge instabilities, which can destroy the plasma facing wall. The project will explore if a new model can describe and control these instabilities.

This project aims at laboratory studies of stellar nucleosynthesis applying ultra-sensitive accelerator mass spectrometry (AMS) measurements. The project will focus on reactions which are essential to open questions in modelling nucleosynthesis in stars, that is where no data exist at all, or are scarce and discrepant; in particular for neutron- and charged-particle induced reactions relevant to the s-and p-process where an extremely sensitive detection method is required. New data for key nuclear reactions will be connected with theory, for testing and improving theoretical predictions. They will be highly beneficial for modelling the respective nucleosynthesis processes in stars and for our understanding of the elemental abundance of our solar system.Read moreRead less
