This has been a team effort, involving a large number of people. Paul Jones and Ilias Livanos contributed to the spatial analysis described in Chapter 4. Andrew Holden and Peter Millar made important contributions to the data analysis and processing. Thanks are also due to Amanda Kerry for word processing and related assistance and to Jackie Wilson for help(More)
The Imaging and Medical beamline at the Australian Synchrotron achieved ;first light' in December 2008. Here, the first experiments performed on the beamline are reported, which involved both X-ray imaging and tomography studies for a range of samples. The use of a plastic-edge phantom for quantitative measurements of contrast and resolution proved to be(More)
The value of using synchrotron radiation diffraction (SRD) for characterising standard reference materials (SRMs), as a supplement to laboratory x-ray powder diffraction (XRD) analysis, has been demonstrated with the National Institute of Standards and Technology LaB6 material NIST SRM 660. Measurements were performed under in vacua conditions with the(More)
The first observation of a true geometrical focus of X-rays well beyond the exit of a paraboloidally tapered glass monocapillary is reported. An intensity gain of 250 +/- 20 into a 6 x 9 mum pinhole for 8 keV X-rays and transmission efficiencies of more than 90% below 20 keV were observed.
An eight-position capillary sample spinning stage has been developed for use in conjunction with the versatile vacuum diffractometer (BIGDIFF) at BL20B at the Photon Factory. BIGDIFF is often used in its powder diffraction mode using powders mounted in capillaries and up to eight imaging plates to record the diffraction pattern from the sample. Using the(More)
VACM-1/CUL5 is a member of the cullin family of proteins involved in the E3 ligase-dependent degradation of diverse proteins that regulate cellular proliferation. The ability of VACM-1/CUL5 to inhibit cellular growth is affected by its posttranslational modifications and its localization to the nucleus. Since the mechanism of VACM-1/CUL5 translocation to(More)
The highly organized morphogenesis of bird feathers holds important phylo- and ontogenetic information on the evolution of birds, organogenesis, tissue regeneration, and the health status of individual animals. Altered topobiological patterns are regularly used as retrospective evidence for disturbed developmental trajectories due to the past exposure to(More)
The powder diffractometer at the Australian National Beamline Facility makes extensive use of imaging plates as a detector system. On this instrument, a Weissenberg screen and translatable imaging plate cassette allow a series of up to 35 complete powder patterns to be taken in rapid succession. The high sensitivity and dynamic range of imaging plates mean(More)
A multiple-imaging-plate detector system and focusing monochromator have been developed and successfully applied to the time-resolved study of phase transitions in Langmuir-Blodgett films by grazing-incidence X-ray diffraction (GIXD). The monochromator described here combines fixed-exit-beam height with sagittal focusing of the second crystal. The design is(More)
