New technology developed by Australia, Sweden and the United States will be applied to major questions about the application of relativistic quantum mechanics to atomic structure and dynamics and spectroscopy, especially including critical issues in quantum electro-dynamics for atomic physics and applications. Discrepancies in quantum electro-dynamics have dominated international debate for decades, with claimed explanations annually failing to reveal the cause. Also a pattern of discrepancies has been seen at X-ray energies in first row metal atoms, with a similar sign and magnitude. A combined experimental an theoretical investigation will aim to reveal new light on these anomalies and serve to develop our understanding of the universe.Read moreRead less

Griffith University's Australian Attosecond Science Facility was established 12 years ago to facilitate internationally leading research into strong-field laser science. The facility is unique in Australia as it has the capability to precisely manipulate highly-amplified and ultra-short light pulses to investigate the dynamics of matter. The scientific outputs from the facility have delivered important new scientific advances in strong-field physics enabling the development of new technologies. This grant will be used to procure an upgraded laser system enabling an order of magnitude enhancement of the output light for the next-generation research and maintaining international competitiveness of Australian investigators in this field.Read moreRead less
Electron-driven radical chemistry in plasmas for emerging technologies. The project aims to study electron interactions with the hydroxyl radical (OH). OH is formed in plasmas and atmospheric environments when energetic particles interact with water. Emerging applications of plasmas in wastewater treatment, sterilisation and medicine will be built around OH chemistry. The high intensity of OH spectral emissions has made them useful for remote sensing atmospheric phenomena and diagnosing plasma p ....Electron-driven radical chemistry in plasmas for emerging technologies. The project aims to study electron interactions with the hydroxyl radical (OH). OH is formed in plasmas and atmospheric environments when energetic particles interact with water. Emerging applications of plasmas in wastewater treatment, sterilisation and medicine will be built around OH chemistry. The high intensity of OH spectral emissions has made them useful for remote sensing atmospheric phenomena and diagnosing plasma properties. However, the poor understanding of electron interactions with OH limits our ability to reliably interpret these results. This project therefore aims to experimentally study electron interactions with the hydroxyl radical. The measured values will be applied in simulations that clarify the role of electron–OH interactions in plasma-like environments.Read moreRead less

This project aims to extend our reach in exploring fundamental physics by exploiting a novel fast pattern-recognition technique and extending its limit beyond the current capacity. The recent discovery of the Higgs boson confirmed the remaining element of the standard model of particle physics, yet many fundamental questions about the microscopic nature of the universe remain. The Large Hadron Collider upgrades provide an opportunity to measure the particle's properties and to discover new physics processes by enabling searches for new particles at the high-energy frontier. This project aims to exploit the unique datasets anticipated, develop key electronic components and new techniques that will expand the physics reach of the ATLAS experiment.Read moreRead less

This project will develop next-generation focused ion beam microscopy and nanofabrication using a novel cold ion source based on photoionisation of a laser-cooled atom beam. The low temperature and complex internal state structure of the constituent atoms combine to allow generation of ions with unprecedented brightness and resolution. We will use three unique and innovative ideas: field ionisation of atoms in so-called 'exceptional' states to reduce chromatic aberration; electron-ion correlations to enhance control of the ions at the nanoscale; and atom-atom interactions to isolate and manipulate individual ions. The new technology will enable advances in semiconductor nanofabrication and material characterisation.Read moreRead less

Australian contribution to CERN large hadron collider experiment upgrade: The discovery of the Higgs Boson with the ATLAS experiment at the CERN laboratory's large hadron collider, has been a highlight for Australian science. Scientists will build upon the foundation of the Higgs discovery to further probe the nature of matter at the finest scales and highest energies. Detailed measurements of the Higgs characteristics will determine if it is as predicted by the Standard Model or whether it admits a variation, signalling new physics. The upgrade in this project will provide for such detailed measurements. It will also allow sensitive probes of new physics, searching for new particles or unexpected interactions.Read moreRead less

This project aims to develop a new generation of bright, laser-like x-ray sources for laboratory use. X-ray sources underpin key diagnostic techniques in materials science, advancing applications from structural engineering through to ore processing and energy storage. However, the limited brightness of present-day laboratory x-ray sources restricts the utility and range of these diagnostic techniques. This research intends to use intense lasers to create microscopic plasmas and drive high harmonic generation. The high harmonic generation process is already used to create laser-like ultraviolet light. By optimising the characteristics of the plasma medium, the project aims to extend bright high harmonic generation to the x-ray regime.Read moreRead less
