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.
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.
Sponsorship
We would like to thank our sponsors and supporters without whom the event would not have been be possible.
Student and Early Career Scientist Support
Thank you to the generous support of the International Union of Crystallography, awards are available to support students and early career scientists to attend Q2XAFS 2023.

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!!
