Welcome to the User Wiki for the Medium Energy X-ray Absorption Spectroscopy Beamlines (MEX-1 and MEX-2)
Potential NEW Users MUST CONTACT BEAMLINE STAFF at as-mex@ansto.gov.au to discuss the proposed measurements before submitting their proposal
Round 3 2025 Update - We will be accepting proposals for microspectroscopy at MEX1 for the first time in 2025/r3. See here for more detail on microspectroscopy capabilities at MEX1. If you are interested in submitting an application to use the MEX1 scanning fluorescence microprobe you MUST CONTACT BEAMLINE STAFF at as-mex@ansto.gov.au AFTER having read the following information.
Round 3 2025 Update - We will be accepting proposals for the Cryostat. Please contact us before submitting a proposal.
Round 3 2025 Update - We will be accepting proposals for in-situ battery cycling. Please contact us before submitting a proposal.
STEP 1. Preparing a MEX Proposal
|
|---|
Choosing an X-ray Absorption Spectroscopy Beamline
MEX-1 Accessible Edges
3.5 - 13.8 keV
MEX-2 Accessible Edges
1.7 - 3.2 keV
MEX-1 Capabilities | MEX-2 Capabilities |
3.5 - 13.8 keV | 1.7 - 3.2 keV |
Room temperature transmission and fluorescence mode, solid and liquid Cryogenic (min 9 Kelvin) transmission and fluorescence mode (contact us before submitting a proposal) Microprobe fluorescence mode | Room temperature drain current and fluorescence in vacuum, solids only Fluorescence in helium (contact us for liquids) |
Ex situ samples In situ (contact us for potential dry in situ capability tests Eg battery cycling) | Ex situ samples ONLY |
Maximum beam size (horizontal x vertical; beam size can be reduced from the maximum using slits) 5 mm x 0.5 mm | Maximum beam size (horizontal x vertical; beam size can be reduced from the maximum using slits) 5 mm x 3 mm |
Estimated scan duration ~20 mins XANES ~35 mins EXAFS (duplicates or triplicates recommended) (Contact us about faster slew scanning) | Estimated scan duration ~20 mins XANES |
