Description
This talk/poster presents the current capabilities and recent facility upgrades at the Centre for Accelerator Science (CAS), within the Australian Nuclear Science and Technology Organisation (ANSTO). Two of our accelerators are equipped with heavy ion nuclear microprobes, capable of focussing and scanning ion beams with micron-level precision. More than 20 ion species can be selected for testing (from H to Au), at energies up to 100 MeV, with continuous beam currents from pA to μA, or in single ion regimes. The recent addition of an ambient air chamber to one microprobe allows for the rapid exchange of samples and enables the testing of biological samples and other materials which can be damaged by vacuum. A new development in our scanning technologies allows for the synchronisation between the of rapid and precise EM scanning and the wider range linear stages on which the sample is affixed, combining the strengths of both methods. This allows for more complex scan patterns to be performed and minimises downtime. CAS scientists and external researchers have recently performed studies involving the effects of space radiation on microchips, satellite photovoltaic technologies, emerging dosimetry technologies, passive (solid) and active (electromagnetic) shielding techniques, and health & radiobiology. ANSTO accepts merit applications/proposals from researchers in universities, research organisations, and industry.
