Summary
Australian dark matter detector for high mass axions. This project aims to provide the necessary equipment to allow an Australian Dark Matter Axion Haloscope, with significantly increased sensitivity by providing a milliKelvin environment and a 14 T magnet to drive axion-to-photon conversions. Dark matter is a fundamental component of the universe yet the nature of its composition is still unknown. There is growing evidence that it is comprised of axions, a low energy, weakly interacting particl ....Australian dark matter detector for high mass axions. This project aims to provide the necessary equipment to allow an Australian Dark Matter Axion Haloscope, with significantly increased sensitivity by providing a milliKelvin environment and a 14 T magnet to drive axion-to-photon conversions. Dark matter is a fundamental component of the universe yet the nature of its composition is still unknown. There is growing evidence that it is comprised of axions, a low energy, weakly interacting particle. The precision measurement tools developed by this project will have the potential to contribute both to the economy, via commercialisation, and to national security, via future applications to radar, communication and the development of engineered quantum systems.Read moreRead less

New High Precision Tests on the Standard Model of Physics and Relativity. Precision microwave oscillators developed at UWA are among the most precise devices for testing the current theories in modern physics, such as relativity and the standard model.

The ability of infrared detectors to directly sense the thermal output of an object has applications in medicine, search and rescue, bushfire detection and in the defence and surveillance industries. The highest performing infrared detectors are photon detectors based molecular beam epitaxy (MBE) grown HgCdTe. The primary aims of this project relate to the fundamental understanding of p-type doping in MBE grown HgCdTe, a current and major difficulty in HgCdTe technology, and the use of such p-type MBE grown layers in conjunction with a newly developed plasma process based n-p junction formation technology to realise novel and innovative infrared detector structures. Such structures would have the ability to revolutionise the use of HgCdTe in infrared detectors and focal plane array applications.Read moreRead less

This project will develop three new clocks for Australia: a laser clock at the leading edge of technology, a novel and compact clock with commercial potential, and a microwave clock for use in the next generation of satellites. The performance advantage conferred by our new devices can deliver economic benefits while also giving the possibility for scrutinizing the laws of physics for evidence that there is something beyond our present formulation.Read moreRead less
Imaging of properties of coherent elastic light scattering from turbid biological media. Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge.

Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer tissue state and morphology indirectly based on phase delay, speckle, and angle-resolved scattering. We will break new ground in correlating the structure and function of in situ epithelial tissue and cells to light scattering enabling, e.g., the detection of mitosis and apoptosis in cells buried in thick, turbid media, and of cancers and precancers in vivo.Read moreRead less
Advances in optical coherence tomography. We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation.

We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation. These advances are aimed at improving resolution to the 1-5 micron range, which should allow a breakthrough to sub-cellular in vivo imaging, making visible sample histology in situ, which is currently not possible. We also plan to make advances in the key area of scanning delay line technology by employing acousto-optics in OCT for the first time. Acousto-optics conveys advantages in no-moving-parts, scan-speed and accuracy.Read moreRead less
