Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on ....Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on twinning. The formation of crystalline twins is known to dictate the strength of the light metal magnesium. A fuller understanding of the effect of twinning on strength in this metal will provide much needed confidence to implement it more widely in energy saving applications.Read moreRead less

Summary
Breaking through the barrier: a new approach to understanding quantum tunneling in nuclear fusion. Experiments have shown major failings of our best predictive model of nuclear fusion. This project will address these failings through a multifaceted research program which will develop and benchmark an enhanced quantum model and test for missing physics by conducting precision fusion measurements for carefully chosen reactions. This project will develop a new technique that exploits fission follow ....Breaking through the barrier: a new approach to understanding quantum tunneling in nuclear fusion. Experiments have shown major failings of our best predictive model of nuclear fusion. This project will address these failings through a multifaceted research program which will develop and benchmark an enhanced quantum model and test for missing physics by conducting precision fusion measurements for carefully chosen reactions. This project will develop a new technique that exploits fission following fusion to directly probe physical processes inside the fusion barrier, which are missing from current models. This integrated approach to fusion will allow us to better predict fusion cross sections, create new elements and exploit radioactive ion beams at new international facilities.Read moreRead less
X-ray Ghost Imaging and Tomography. This project aims to achieve safer, faster, and cheaper 3D X-ray imaging through a technique known as ghost imaging. X-ray imaging provides valuable information about internal structures, however, X-rays are carcinogenic and exposure (or dose) should be limited. Ghost imaging is an unconventional technique developed with visible light that has many potential benefits over conventional imaging. This research group are world leaders in ghost imaging and expect t ....X-ray Ghost Imaging and Tomography. This project aims to achieve safer, faster, and cheaper 3D X-ray imaging through a technique known as ghost imaging. X-ray imaging provides valuable information about internal structures, however, X-rays are carcinogenic and exposure (or dose) should be limited. Ghost imaging is an unconventional technique developed with visible light that has many potential benefits over conventional imaging. This research group are world leaders in ghost imaging and expect to develop software and hardware techniques to realise its potential and extend it to ghost tomography. The focus of this project is on reducing cancer risk in medical imaging, and allowing real-time quality control for 3D printing in safety-critical industries such as aerospace.Read moreRead less
Sulfur isotope fractionations in Earth evolution. Sulfur isotopes provide a unique window into the major events in Earth's history. Techniques have been developed for measuring all four sulfur isotopes, including the low abundance sulfur-36 (0.02 per cent) to 0.2 per mil, in situ for sulfides. This project will make innovative technological developments to the counting system to extend this capability to the lower count rates obtained from sulfates. This will open windows for research on proces ....Sulfur isotope fractionations in Earth evolution. Sulfur isotopes provide a unique window into the major events in Earth's history.

This project will make innovative technological developments to the counting system to extend this capability to the lower count rates obtained from sulfates. This will open windows for research on processes occurring in the early solar system, atmospheric and hydrologic conditions in the Archean, ore-forming processes, and evolution of life on Earth.

Reaching the superheavy elements: a quantitative understanding through integrating new reaction time measurements with theoretical models. The project will develop new experimental methods to give unique insights into the interplay of quantum effects in nuclear fusion reactions forming heavy elements. The results will guide theoretical model developments to enhance understanding, and predict optimal opportunities to form new elements and isotopes with future rare isotope accelerators.
Quantum thermalisation: a new framework for nuclear collisions. This project aims to quantify and model the processes that lead to quantum thermalisation in nuclear collisions. Thermalisation is critical to the synthesis of new superheavy elements, production of medical isotopes, and creation of heavy elements in the cosmos. Yet quantum thermalisation in nuclear systems is not understood, causing models to be wrong by up to a factor of 100. This project will determine the routes to thermalisatio ....Quantum thermalisation: a new framework for nuclear collisions.

The project will enable new fundamental tests of quantum mechanics and benefit broader applications of nuclear collisions.Read moreRead less
Mapping the microscopic pathway to dissipation in quantum nuclear collisions. Nuclear reactions power the universe and produce all the chemical elements, whose abundances are a sensitive probe of energetic cosmic events. Our new concepts and experiments will probe the boundaries of the quantum world, guide applications of international radioactive isotope accelerators and address the problem of lithium abundance in the cosmos.
