Summary
Silicon Imaging Device Construction Facility - Wirebonder. The development of state-of-the-art, high precision semiconductor imaging devices (for high energy particle physics, synchrotron science and medical imaging ) requires a significant capability in modern assembly facilities.

The development of state-of-the-art, high precision semiconductor imaging devices (for high energy particle physics, synchrotron science and medical imaging ) requires a significant capability in modern assembly facilities. In constructing test and 'production' modules consisting of fine-grained, multi-channel bare silicon or other semiconductor imaging devices and custom electronic chips, a high-reliability, highly flexible wire-bonding machine is an essential tool. The international reputation from success in several challenging projects under difficult conditions, gained by the Chief Investigators has resulted in several more projects being planned in addition to a foreseen program of device development. A modern wirebonder, to replace the existing 30 year-old machine, has become critical to maintain our leading position in this area.Read moreRead less
Rare isotopes as tracers of prosthesis debris. The incidence of knee replacement surgery in Australia is 30,000 per year. Limited by wear debris, the lifespan of knee implants is only 10-15 years and can be much shorter. Due to increasing life expectancy, many patients need several surgical procedures. As a multi-disciplinary team of materials-, isotope-tracing- and medical-experts, we aim to understand and monitor wear debris in prostheses. Knee replacement surgery alone imposes a high burden o ....Rare isotopes as tracers of prosthesis debris. The incidence of knee replacement surgery in Australia is 30,000 per year. Limited by wear debris, the lifespan of knee implants is only 10-15 years and can be much shorter. Due to increasing life expectancy, many patients need several surgical procedures. As a multi-disciplinary team of materials-, isotope-tracing- and medical-experts, we aim to understand and monitor wear debris in prostheses. Knee replacement surgery alone imposes a high burden of annually half a billion dollars on the Australian health budget. Controlling and reducing wear debris in prosthesis joints would reduce these costs and improve patients' quality of life.Read moreRead less
Auger-electron yields of medical radioisotopes. Large numbers of Auger electrons are emitted during the decay of many medical isotopes. Auger electrons have a short range and a strong ability to break chemical bonds. However no measurements of the number of Auger electrons per nuclear decay exist in the critical low energy regime. Calculated Auger yields are incomplete and inconsistent. Building on unique Australian expertise and instrumentation, and performing both calculations and measurements ....Auger-electron yields of medical radioisotopes. Large numbers of Auger electrons are emitted during the decay of many medical isotopes. Auger electrons have a short range and a strong ability to break chemical bonds. However no measurements of the number of Auger electrons per nuclear decay exist in the critical low energy regime. Calculated Auger yields are incomplete and inconsistent. Building on unique Australian expertise and instrumentation, and performing both calculations and measurements, his project aims to determine the number of Auger electrons per nuclear decay accurately for medical isotopes. The outcome will be accurate dose data for radioisotopes, plus essential knowledge to develop new cancer treatments based on Auger electrons, which target a fraction of a cell.Read moreRead less
High Energy Heavy Ions in Materials Science. The outcome of this project is to develop a more accurate predictor of the rate of energy loss of high energy heavy ions in solids which will have profound implications in the use of these particles in ion implantation, materials analysis and medical physics applications. It will contribute to the development of new high technology materials and to the application of high energy ions to medical treatment procedures.
High-average-power all-solid-state lasers based on new crystalline Raman materials. We have recently made significant advances in development of all-solid-state intracavity Raman lasers generating multiwatt average powers in the near infrared and (by frequency doubling) visible spectrum, with important applications in biomedicine and remote sensing.

We have recently made significant advances in development of all-solid-state intracavity Raman lasers generating multiwatt average powers in the near infrared and (by frequency doubling) visible spectrum, with important applications in biomedicine and remote sensing. A new generation of Raman crystals, especially tungstates, offer superior optical, mechanical and thermal properties, promising high Raman gains and choice of Stokes frequency shift. The project will investigate a range of key issues for these materials including control of the Stokes wavelength, associated polarisation control, and pump-resonator configurations giving maximum Raman laser power and efficiency. The project will lead to state-of-the-art source technology with outstanding prospects for commercialisation and practical application.Read moreRead less
Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently avai ....Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently available. Using the ultraviolet laser fibre processing expertise already developed at Macquarie University, we propose to develop and characterise novel fibre-based devices which would allow controllable delivery of light sideways.Read moreRead less
