Abstract
Introduction: The Australian Synchrotron is powerful source of electromagnetic radiation that produces photon energies up to 3 GeV. The powder diffraction (PD) beamline at the Australian synchrotron produces bright, highly-collimated X-ray beams that, when combined with the state-of-the-art MYTHEN II microstrip detector, are ideal for time-resolved X-ray powder diffraction experiments requiring rapid, high resolution data collection. In addition, the powder diffraction beamline exploits the unique properties of synchrotron radiation to offer tunable wavelengths (6 - 30 keV, 2.07 - 0.41 Å) to minimise sample absorption and fluorescence, provide high flux and good S/N for increased detection limits. Since beginning user operations in 2008, 490 user experiments have been performed at the powder diffraction beamline. This contribution describes and demonstrates the capabilities offered by the beamline, particularly for planetary sciences and geosciences applications, highlighting the unique in-situ experiments that have not only produced successful scientific outcomes, but have pushed the boundaries in many cases.
