The XAS beamline employs hard X-rays, spanning 6.5 - 31 keV. Please see the XAS page on the Australian Synchrotron website here for more details on the XAS photon delivery system. The energy range is accessed via three ‘beamline modes’ covering the low (6.5-9 keV aka Mode 1), medium (9-19 keV aka Mode 2), and high (15-31 keV aka Mode 3) energies. Note that to setup a beamline mode, or to switch between modes, approximately one day of downtime is required. Therefore, all Mode 1 experiments are scheduled back-to-back, followed by all Mode 2 experiments, then all of Mode 3.
If users would like to analyse edges in different energy modes, they MUST submit a separate proposal for each mode. We recommend that separate proposals have the same content but different sample tables, and be designated ‘Part 1,' ‘Part 2,' etc, in their proposal title.
