Crystalline phase determination, polycrystallinity, strain, grain orientation as well as defect structure, migration and organisation are fundamental to the understanding of materials’ properties. The MMC beamline is the only facility planned for the Australian Synchrotron that will enable these properties to be spatially resolved at the micron scale.
We present the current design and...

The Macquarie University-Australian Synchrotron D-DIA apparatus is a large-volume solid-media apparatus for high pressure, high temperature in-situ x-ray experiments. The apparatus can subject a sample volume of up to 5 mm^3 to pressures to 6 GPa and temperatures to 1500 °C.
During 2016/2 initial experiments were conducted on the XAS beamline. Uranium and Thorium L3-edge transmission XANES...

Small angle X-ray scattering (SAXS) is an extremely useful tool for analysing protein structures that is becoming increasingly popular. SAXS displays a number of advantages over other techniques, but radiation damage and sample consumption limit the utility of the technique to the wider protein community. Of the various avenues being pursued to circumvent radiation damage, we have focused...

Sample positioning and rotation on the X-ray beam are critical experimental parameters for a successfully experiment . This becomes exacerbated when handling small crystals on a micro-focus beam like the one provided by the MX2 beamline at the Australian Synchrotron. Here it is paramount that the centre of rotation is on the same location as the X-ray beam. For one hand, any procession,...

This presentation gives an overview of the development and comparison of different sample preparation techniques for presenting samples to the Far-IR and IR beam line at the Australian Synchrotron.
We have investigated using polyethylene (PE), polytetrafluoroethylene (PTFE), polyvinylacetate (PVA), paraffin, and mixtures, as matrixes for pellets.
We have also trialled pressing pure...

Richly detailed high definition elemental images are routinely collected during experiments at the X-ray Fluorescence Microscopy (XFM) beamline [1]. In addition, complex 3D data sets may be collected - X-ray fluorescence tomography and/or XANES image stacks. For many experiments there can be up to ¼ TB of raw data to process from a 3 to 4 day visit.
This presentation will describe the...
