Australian scientists and engineers require immediate access to frontier T-ray (terahertz radiation) technology to solve pressing current problems in semiconductor nanostructures and emerging problems in fields as diverse as biophysics and national security. Recent innovations now make practical the production of bursts of terahertz radiation by applying ultrafast optical pulses to photoconductive or electro-optic media, facilitating unparalleled time-resolved spectroscopy and imaging. The state-of-the-art equipment to be purchased and installed at Wollongong will enhance the existing excellent terahertz infrastructure (unique spectrometers, optically-pumped molecular laser) and efficiently service researchers in the dynamic Sydney (UTS, UNSW) - Wollongong (UoW) - Canberra (ANU) corridor.Read moreRead less

Australia is a world leader in the development of High Frequency (HF) radar surveillance systems, such as JORN (Jindalee over-the-horizon radar). However, Australia's ability to support these operations and remain a leader in these fields depends on its capacity to nurture expertise and train new personnel in these areas. The new HF radar system will play a crucial role in this respect, providing (i) high-level training in radar technology and associated science, (ii) a test bed for the development of new instrumental and data analysis techniques, (c) new information on the source of ionospheric perturbations that can affect the performance of JORN, and (d) data important for Australia's space weather prediction community, via IPS (Ionospheric Prediction Service) Radio and Space Services.Read moreRead less
