Commission on XAFS

Q2XAFS 2023

The International Workshop on Improving Data Quality and Quantity in XAFS Spectroscopy (Q2XAFS2023) will be held at the Australian Synchrotron in Melbourne (Australia), August 17-19, 2023. This is a Satellite Meeting of the IUCr Congress. The workshop aims to bring together experts in the field of X-ray Absorption Spectroscopy to discuss aspects of the technique that affect data quality in XAFS experiments.

Q2XAFS2023 will provide a forum for discussions with the goal of reviewing international standards and protocols and developing revised recommendations for best practice when performing XAFS experiments. The workshop will be attended by scientists working at international facilities as well as academics.

The event aims to cover the following elements:

  • Portability of XAFS data and scientific content between beamlines and facilities (e.g. data formats, traceability and data provenance)
  • Data repositories and access to data
  • Precision and reproducibility of data and data treatment
  • XAFS data and analyses for industry (e.g. standards, quality control)
  • New analytical methods
  • Discipline-specific data standardisation
  • Fluorescence XAFS data
  • Theory development underscoring data quality and quantity

Call for Poster Award 

Q2XAFS2023 will include a poster session for 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 the Q2XAFS and get the prize!!

Statement on Gender Balance at Q2XAFS 2023
The Q2XAFS Organizing Committee fully supports and promotes gender equality in accordance with the IUCr policy
We will ensure gender equality in our committees (including the Organizing Committee itself), among our lecturers and participants and pay special attention to the gender balance in evaluating bursary applications.
In accordance with IUCr policy, our gender statistics are here. We have developed a committee and lecturer policy, setting up the 40% ratio as a bare minimum to be looked for by the organizers. More specifically, the ratio in the International Programme and Local Organizing Committees is 44% (9 people; 4/9) and 50% (8 people; 4/8) respectively. This ratio is also looked for in the lecturers though with more flexibility, given that not all fields have the same representation. The above ratios compared to previous information on past IUCr Q2XAFS workshop in 2017, where only 20% and 33% members of the International Programme and Local Organizing Committees, respectively, were women, clearly shows the positive evolution of the XAFS community to a fair gender balance.
Further information can be found on the web site of IUCr’s Gender Equity and Diversity Committee GEDC ( This page contains a code of conduct, a GEDC conference speaker statement and a toolkit for conference organisers.

Scientific Freedom Policy Statement
The Organizing Committee of Q2XAFS shall observe the basic policy of non-discrimination and affirms the right and freedom of scientists to associate in international scientific activity without regard to such factors as ethnic origin, religion, citizenship, language, political stance, gender, sex or age, in accordance with the Statutes of the International Council for Science. At Q2XAFS no barriers will exist which would prevent the participation of bona fide scientists.

Diversity, Equality and Inclusion Statement
We welcome all crystallographers and scientists working in related fields, regardless of their ethnic origin, race, citizenship, language, political views, gender, sex, sexual preferences, physical disabilities and age. We strive to create a culture of diversity, equality and inclusion.
