Multiple-wavelength powder diffraction using imaging plates at the Australian National Beamline

The Australian powder diffractometer at the Photon Factory is capable of recording multiple powder‐diffraction scans in less than 5 min per pattern using imaging plates in Debye–Scherrer geometry. This, coupled with incrementing the X‐ray beam energy in suitably small steps (down to ∼2 eV) between e...

Description
Summary:The Australian powder diffractometer at the Photon Factory is capable of recording multiple powder‐diffraction scans in less than 5 min per pattern using imaging plates in Debye–Scherrer geometry. This, coupled with incrementing the X‐ray beam energy in suitably small steps (down to ∼2 eV) between exposures, allows fast collection of anomalous diffraction data. Data collected from a copper oxide‐based superconductor at energies near the Cu K‐absorption edge are presented, along with an account of the technique used to extract multiple‐exposure powder‐diffraction data from imaging plates.
