Mileura Widefield Array: A New Low Frequency Telescope. A new radio-quiet site for international radio astronomy is being developed at Mileura in Western Australia. We have constructed a low frequency test array on the site, and established that the site is excellent for radio astronomy. We plan to build a telescope which will observe the early universe, when stars and galaxies where first born. This will be the first telescope capable of this type of measurement of the early universe. In addi ....Mileura Widefield Array: A New Low Frequency Telescope.

Atomic Ionization on the Attosecond Time Scale. Electrons emit light, carry electric current, and bind atoms together to form molecules. Insight into their atomic-scale motion is the key to understanding the functioning of biological systems, developing efficient sources of x-ray light, and speeding up electronics. Capturing this electron motion requires attosecond (one quintillionth of a second) time resolution. Our research aims to understand and accurately model fundamental atomic processes ....Atomic Ionization on the Attosecond Time Scale.

Insight into their atomic-scale motion is the key to understanding the functioning of biological systems, developing efficient sources of x-ray light, and speeding up electronics. Capturing this electron motion requires attosecond (one quintillionth of a second) time resolution. Our research aims to understand and accurately model fundamental atomic processes taking place on the attosecond time scale. This research project will further enhance our reputation in an area where Australian theorists are preeminent, and the research training will produce PhD graduates with the skills essential in a multitude of nano-technology applications.

Spin-dependent interactions: a fundamental basis for spin-electronics. This project will establish a comprehensive understanding of spin-dependent interactions and correlated behaviour of multi-electron systems that are responsible for spin-relaxation, spin transport and spin coherence in spin-electronic devices. Our approach is based on the spin-resolved two-electron coincidence spectroscopy that is inherently suited for studying electronic correlations.

Our approach is based on the spin-resolved two-electron coincidence spectroscopy that is inherently suited for studying electronic correlations. Systematic investigations of spin-dependent interactions in atoms, molecules and ultrathin films will increase understanding of magnetic (spin) properties of artificially structured materials with reduced dimensionality for the benefit of nanotechnology. This understanding will be used to design and control, at the quantum mechanical level, the building blocks of spin-electronic devices.Read moreRead less

Summary
Ultra High Resolution Electron Recycling Spectrometer. Electron collisions with atoms and molecules provide enormous versatility through the transfer of large amounts of angular momentum and the ability to excite dipole forbidden states. However a lack of energy resolution severely restricts the processes that can be studied.

However a lack of energy resolution severely restricts the processes that can be studied.
We propose to construct a unique, ultra-high resolution, electron recycling spectrometer using a radical new design. State-of-the-art spectroscopic studies of atoms and molecules will be enabled, including the dynamics of near-threshold processes, the formation of transient states and the examination of processes such as rotational excitation and dissociative attachment in molecules - important in a number of gas-discharge based devices.
