This research will develop a new x-ray diffraction technique for characterization of silicon-germanium-carbon semiconductor alloys. These are the basis for the new generation, ultra-high speed broadband telecommunication devices. The research will establish a new theoretical methodology for fundamental studies of x-ray scattering phenomena in compound strain-compensated materials. The experiments will be carried out using the state-of-the-art laboratory and synchrotron radiation facilities in Australia, Japan and France. The project involves direct collaboration with IHP Germany, the world-leading semiconductor developer. Highly qualified postgraduate students will be extensively trained in modern synchrotron experiments, x-ray diffraction theory and semiconductor technology during the project.Read moreRead less
DYNAMICS OF EARTH'S RADIATION BELTS. Space weather is produced by rapid variations in wave fields and particle populations in near-Earth space, and has many effects. These include damage to spacecraft (causing operational anomalies and loss of service), degrading the performance of GPS, space-ground, HF radio and cable-based networks, and affecting surveillance radars. The core aim of this project is to improve knowledge of the waves and particles causing these effects. While being important to ....DYNAMICS OF EARTH'S RADIATION BELTS.

The core aim of this project is to improve knowledge of the waves and particles causing these effects. While being important to aerospace engineers, this work also consolidates Australia's international space profile and provides excellent training in this field. Since space weather causes significant radiation exposure to aircraft crew and passengers this work also has broader ramifications.Read moreRead less
Ring Current and Radiation Belt Dynamics. Outbursts of energy from the Sun manifest themselves as geomagnetic storms in the Earth's magnetosphere. These storms can severely disrupt and damage advanced technological systems operating on the ground and in space.

Outbursts of energy from the Sun manifest themselves as geomagnetic storms in the Earth's magnetosphere. These storms can severely disrupt and damage advanced technological systems operating on the ground and in space. Operational spacecraft may experience anomalies, pipelines in the long term may corrode and the performance of GPS navigational systems, HF (High Frequency) communications systems, mobile/cell telephone networks and defence surveillance radars may be degraded. It is important to understand the magnetospheric conditions contributing to these problems. This research identifies relevant mechanisms. It also enhances Australia's international space research profile, contributes to Australia's future and supports excellent postgraduate training.Read moreRead less
