Q2XAFS is a symposium series bringing together experts in the field of X-ray Absorption Spectroscopy to discuss aspects of the technique that affect data quality in XAFS experiments.

The latest iteration of Q2XAFS was run at Australian Synchrotron, ANSTO, as a satellite of the IUCr Congress 2023 in Melbourne, Australia. The symposium provided a forum for discussions with the goal of reviewing international standards and protocols and developing revised recommendations for best practices when performing XAFS experiments. Synchrotron staff, experts, and community members from around the globe joined the workshop.

Attendees joining Q2XAFS 2023 at the Australian Synchrotron.

Following the workshop, a roundtable discussion was held at the University of Melbourne to progress and consolidate discussions from the workshop (by invitation).

Venue

Q2XAFS 2023 was held at the award-winning National Centre for Synchrotron Science at the Australian Synchrotron in Melbourne, Australia. Following closing of the workshop at the Australian Synchrotron, the event closed with a dinner in Melbourne's CBD.

Program

Session 1: Sharing and re-using XAS data
  • Data formats (plain text, XDI, xasCIF, NeXus/HDF5, CIF)
  • Metadata (Essential meta data, ontology of XAFS related terminology)
  • XAFS databases
  • Comparability of XAFS data (Round Robin)
Session 2: Improving the interpretation of XAS data
  • Quantification of uncertainties during EXAFS data evaluation and propagation of uncertainties
  • Quantification and correction of experimental uncertainties (dark currents, dead time etc.)
  • Quantifying uncertainties in XANES evaluation methods (PCA etc.)
  • Novel methods (Machine Learning, AI…)
Session 3: Improving the quality of XAS measurements
  • Bio and other fragile samples (beam damage)
  • Extreme conditions (ultrafast, high-pressure, in-operando)
  • Fast measurements (Q-XAFS, dispersive XAFS)
Session 4: Improving the reporting of XAS results
  • General reporting guidelines for XAS publications
  • IUCr and CXAFS reports
  • Assessing experimental data quality
  • Including uncertainties in pre-processed data and reported results
  • Specific challenges and reporting for photon in/photon out spectroscopies
  • Specific challenges and reporting for lab-based XAFS

Early Career Poster Award

Q2XAFS2023 will include a poster session with a focus on early career scientists, including students and post-docs. Please present your achievements and your own problems concerning XAFS data quality including, experimental and theoretical efforts. To promote your participation, the IXAS has created poster awards based on the kind donation from Dr. Matthew Newville and Dr. Bruce Ravel, who received the Edward Stern Prize in XAFS2022 in Sydney.  We need all young powers to blow in a new wind.  Please join Q2XAFS and get the prize!!
