155. Micro Materials Characterisation (MMC) Beamline: Scope and Focus

Prof. Andrea Gerson (Blue Minerals Consultancy)

25/11/2016, 13:30

Technique Development

Oral

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...

171. First experiments with D-DIA apparatus on XAS

Dr Jeremy Wykes (Macquarie University)

25/11/2016, 14:00

Technique Development

Oral

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...

249. Coflow and Fast-SEC Improvements on the SAXS/WAXS Beamline

Dr Nigel Kirby (Australian Synchrotron), Dr Tim Ryan (Australian Synchrotron)

25/11/2016, 14:15

Technique Development

Oral

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...

252. The MX2 goniometer story: the old, the current and the new one

Dr David Aragao (Australian Synchrotron)

25/11/2016, 14:30

Technique Development

Oral

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,...

256. Optimising sample preparation for solids, pellets, liquids and solutions for Far-IR and IR analysis at the Australian Synchrotron

Ms Josie Nunn (Flinders University SA)

25/11/2016, 14:45

Technique Development

Oral

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...

205. How to get the most from your XFM data: GeoPIXE analysis on MASSIVE

David Paterson (Australian Synchrotron)

25/11/2016, 15:00

Technique Development

Oral

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...
