66. X-ray ghost imaging: Line scans, radiography and tomography

Prof. David Paganin (Monash University)

Technique Development

Oral

Ghost imaging is a new field of optics. Emerging from the field of quantum optics and initially believed to be underpinned by quantum-mechanical “spooky action at a distance”, the field has rapidly achieved prominence in studies using classical visible light [1].

In ghost imaging, photons from a source pass through a speckle-making mask, leading to a spatially random pattern “A” being...

109. Small Angle Neutron Scattering Capability at the Australian Nuclear Science and Technology Organisation

Kathleen Wood (Australian Nuclear Science and Technology Organisation)

Technique Development

Oral

Small angle scattering is a technique that provides information about the size and overall shape of structures on the nanoscale. Although not a ‘real space’ technique such as microscopy, small angle scattering presents certain advantages over microscopy such as the ability to study molecules and their self-assembly in solution. Samples can then readily be studied under a range of conditions...

99. Synchrotron Radiotherapy of Pet Cadavers at the Imaging and Medical Beamline in Anticipation of Live Veterinary Animal Trials

Oral

Introduction

Hutch 3B at the Australian Synchrotron’s Imaging and Medical Beamline (IMBL) offers the unique opportunity to deliver Synchrotron Radiotherapy (SR) to pet animals and human patients with much larger field sizes than is possible in Hutch 2B. Hutch 3B, located 140m away from the Synchrotron X-ray source, allows for a minimally-divergent beam and clinically comparable...

65. Australian Synchrotron MX beamlines - The Impact of Dectris Eiger Detectors

Daniel Eriksson (Australian Synchrotron)

02/12/2019, 11:50

Technique Development

Oral

The Australian Synchrotron MX beamlines support a user community that includes both Structural Biology (PX) and Chemical Crystallography (CX). Addressing the needs of both communities leads to a number of compromises regarding the design and implementation of the beamline infrastructure; however it also leads to unique opportunities.
Both MX Beamlines have recently had detector upgrades; MX2...

84. Microscopy capabilities at the Australian Synchrotron

Dr David Paterson (Australian Synchrotron)

02/12/2019, 12:05

Technique Development

Oral

Microscopy capabilities at the Australian Synchrotron include Infrared Microscopy (IRM) and X-ray fluorescence microscopy (XFM) [1].

Infrared Microscopy or Fourier Transform Infrared (FTIR) spectroscopy can provide spatially resolved spectroscopic information on organic and inorganic compounds. High brilliance synchrotron IR enables high signal-to-noise ratios at spatial resolutions between...

48. What Sample Environment Can Do For You

Norman Booth (ANSTO), Rachel White (ANSTO)

02/12/2019, 12:20

Technique Development

Oral

Sample environment at ACNS comprises a varied suite of instrumentation and equipment. In the last 12 months this has expanded with two new cryostats and a new helium dilution refrigerator being commissioned. We will talk about our capabilities, how to get the best out of our equipment and some recent unique and interesting sample environment set ups. These include a sample changer on our 5T...

111. Iterative energy self-calibration of Fe XANES spectra

Michael Jones (QUT)

02/12/2019, 12:35

Technique Development

Oral

Determining the oxidation state of Fe through parameterisation of XANES spectral features is highly dependent on accurate and repeatable energy calibration between spectra. Small errors in energy calibration can lead to vastly different interpretations. While a simultaneous measurement of a reference foil is often undertaken on X-ray spectroscopy beamlines, other beamlines measure XANES...
