This project aims to develop an underground integrated laboratory at Stawell Gold Mine in Victoria to host the Southern Hemisphere's first-ever direct-detection dark matter experiment. Following the Higgs boson discovery, the direct detection of dark matter is seen as the next major challenge for particle physics. This project sees Australian physicists team up with local and international partners in research and industry to join the search for dark matter. This Australian experiment aims to help to confirm or deny current results from Northern Hemisphere experiments. As the mine nears the end of its working life as a gold mine, this project is expected to benefit the local economy and provide opportunities for education and outreach.Read moreRead less
Advanced shield materials for compact fusion energy. We aim to predict how materials used for shielding sensitive components in nuclear fusion reactors will degrade over time. We will use this knowledge to design advanced alloys for radiation shield, which are critical for the development of more compact fusion reactors design, with lower construction cost, and shorter assembly time. These advanced shield materials may also be used in other applications in radiation fields (e.g. space, nuclear m ....Advanced shield materials for compact fusion energy.

Enhancing the performance of high voltage direct current power cables by studying space charge accumulation in their synthetic polymeric insulation. Synthetic polymeric insulation has proved very successful in high voltage alternating current power transmission cables, and cable manufacturers have therefore sought to use it in high voltage direct current (HVDC) cables, for which there is a rapidly growing demand. Yet the accumulation of space charge in such cables presently severely limits the m ....Enhancing the performance of high voltage direct current power cables by studying space charge accumulation in their synthetic polymeric insulation. Synthetic polymeric insulation has proved very successful in high voltage alternating current power transmission cables, and cable manufacturers have therefore sought to use it in high voltage direct current (HVDC) cables, for which there is a rapidly growing demand. Yet the accumulation of space charge in such cables presently severely limits the maximum operating voltage and transmitted power. Nearly all this space charge is due to the temperature gradient in the insulation. We will analyze space charge profiles in polyethylene and other synthetic polymers, and derive basic scientific data which will inform the design of HVDC cables with greatly enhanced performance.Read moreRead less
Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to ....Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to improve radiotherapy treatments in patients with small lesions with sizes of up to a few centimetres. This will lead to an improved outcome for some cancer patients.Read moreRead less
Neuroimaging changes underpinning improvements in cognition in the elderly. Natural supplements are often used to improve brain and cognitive function, however, we do not know how these supplements work in the brain. Using novel brain imaging scans, the project will investigate whether 12-month administration of two promising natural supplements improves brain markers of ageing and cognitive decline in an elderly population.
Core loss mechanisms in soft magnetic nanostructures. This project aims to clarify the mechanism of power losses in magnetic cores used in the petrol-electric hybrid cars by investigating the relationship between the core losses and magnetic correlation lengths in iron alloys. This project expects to generate new knowledge on the effect of magneto-mechanical interaction on the anomalous core loss in iron based alloys. The intended outcomes include an experimental confirmation of the random aniso ....Core loss mechanisms in soft magnetic nanostructures. This project aims to clarify the mechanism of power losses in magnetic cores used in the petrol-electric hybrid cars by investigating the relationship between the core losses and magnetic correlation lengths in iron alloys. This project expects to generate new knowledge on the effect of magneto-mechanical interaction on the anomalous core loss in iron based alloys. The intended outcomes include an experimental confirmation of the random anisotropy model, a major theoretical model in nanostructured materials and identification of ideal magnetic domain configurations for lower power losses. These intended outcomes should bring great benefits to the development of low-carbon vehicle technologies for sustainable motorisation in Australia.Read moreRead less
Nanostructured soft magnetic alloys for low-carbon cars. The aim of this project is to prepare iron-based magnetic nanostructures that exhibit a magnetic induction of 1.9 tesla and core losses lower than those of iron-silicon steels, which would deliver smaller and efficient magnetic cores for petrol-electric hybrid cars. Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of ....Nanostructured soft magnetic alloys for low-carbon cars. The aim of this project is to prepare iron-based magnetic nanostructures that exhibit a magnetic induction of 1.9 tesla and core losses lower than those of iron-silicon steels, which would deliver smaller and efficient magnetic cores for petrol-electric hybrid cars. Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of magnetic softness. The project aims to systematically investigate the effect of metalloid and micro-alloying elements on the nano-crystallisation behaviour of the precursor amorphous alloys in order to identify the alloy composition and processing conditions for preparing magnetically soft nanostructures.Read moreRead less
Soft magnetic nanostructures for clean automotive technologies: origin of induced magnetic anisotropies. This project will clarify the mechanism of annealing-induced magnetic anisotropies in magnetic nanostructures and thereby establish a basis for further alloy development of efficient core materials for electric motors. The project outcomes will potentially lead to a significant reduction of the heat loss in petrol-electric hybrid cars.
