The Australian National Beamline Facility
The ANBF is a multi-capability hard X-ray beamline installed at the 2.5 GeV Photon Factory second generation synchrotron light source, located in Tsukuba Science City in Japan. The ANBF project was funded by a consortium comprising the Department of Industry, Science and Tourism (DIST), Australian Research Council (ARC), ANSTO, Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australian National University (ANU), University of New South Wales (UNSW) and the University of Sydney, to provide routine access to synchrotron radiation for Australian science.
The ANBF is installed on a bending magnet port, beamline 20B, at the Photon Factory. It delivers monochromatic synchrotron X-rays in the energy range 4.5 - 20 keV to two experimental stations in a single hutch.
The primary instrument is a multi-configuration vacuum diffractometer which uses image plates as its primary detector system. The diffractometer can be configured as an X-ray camera in Debye-Scherer and Weissenberg geometries, or as a two circle diffractometer, a triple crystal diffractometer and a Bonse-Hart small angle scattering diffractometer.
Its capabilities are:
- High Resolution Powder Diffraction using image plates or conventional detectors
- Time resolved powder diffraction
- Grazing incidence (solid surface)
- X-ray diffraction and reflectometry
- Triple crystal diffraction
- Small angle scattering
An optical table behind the diffractometer functions as a second experimental station, primarily used for X-ray absorption spectroscopy: XAFS and XANES. Instrumentation includes a standard transmission detection system (ion chambers), a Lytle ion chamber fluorescence detector, and a 10 element germanium fluorescence detector. A cryogenic sample environment stage is planned. Other experiments can be performed on the second station. Recent examples include X-ray micro-beam optics and applications and phase contrast imaging.
