XAS 2023 @ BNL
2023-10-10 - 2023-10-12 | Brookhaven National Lab, Islip, NY, United States
XAS 2023: Fundamentals of XAS Data Analysis: A Hands-on Tutorial
Hosted by Brookhaven National Laboratory, October 10–12, 2023: https://www.bnl.gov/xascourse/index.php
About this Course
X-ray absorption spectroscopy is a core technique of the DOE synchrotron user facilities and attracts diverse scientific communities. This 3-day course offered by NSLS-II experts will introduce XAS data analysis for new and prospective users and provide an opportunity to perform real experiments at NSLS-II XAS beamlines. The first day will be devoted to fundamentals of XAS analysis, data reduction and processing, and basics of XAS experiments and instrumentation.
Participants will be trained hands-on on XAS data analysis of increasing complexity. Modern XAS methods such as high-resolution spectroscopy will also be introduced. On the third day, the participants will participate in the experiments at XAS beamlines and analyze the data they collect.

EXAFS-50 Symposium
2023-10-30 08:00 - 2023-10-31 17:00 (America/New_York) | Brookhaven National Lab, Islip, NY, United States
https://www.bnl.gov/exafs-50/
This is a two-day Symposium (“EXAFS-50”) that will be devoted to marking the 50th anniversary of discovery of EXAFS. The workshop will bring together the scientists that will talk about the past and present of EXAFS technique and cover topics discussing its future potential and applications. EXAFS is one of the major synchrotron techniques at the DOE light sources and the workshop’s scope directly supports the mission of DOE to establish leadership in advanced characterization at the DOE large user facilities.

XAFS 2023 Short Course on XAFS, BNL
2023-11-01 - 2023-11-03 | Brookhaven National Lab, Islip, NY, United States
Application deadline: August 31, 2023 https://www.bnl.gov/xafscourse/
Every year Brookhaven National Laboratory offers a three-day training course to those interested in learning about the use of x-ray absorption spectroscopy methods. This year, the course will be offered on site November 1–3, 2023. It continues the annual tradition of gathering a group of scientists, active in the field, to share their expertise with those interested in learning about the use of x-ray spectroscopy methods in their research.
The course will be useful for those scientists interested in learning advanced XANES and EXAFS methods, including, tentatively, molecular dynamics EXAFS (MD-EXAFS), reverse Monte Carlo EXAFS (RMC-EXAFS), machine learning – assisted XANES and EXAFS (ML-XANES and ML-EXAFS), and data analysis and are interested in advanced modeling methods applicable for nanomaterials research.
During the last day of the workshop, as has been our tradition since the inception of Brookhaven XAFS short courses, the instructors will divide participants in groups for in-depth problem solving, data analysis and modeling, to best match participants and their research interests. There will be Q&A sessions on the subject of the lectures on the first and second days of the workshop. X-ray spectroscopy is one of the main techniques of the DOE light sources, and the course supports the DOE mission by educating new users in the applications of this technique.
Course participants will be limited and selected based on their application materials.
Wednesday, November 1 and Thursday, November 2 will be devoted to lectures and demonstrations of the software packages.
Friday, November 3 will be devoted to the practical session, in which participants will practice problem solving methods discussed in the previous days. Registered participants will have an option to analyze their own data, in addition to the projects chosen for training purpose.

Q2XAFS 2024
2024-07-01 - 2024-09-30
Q2XAFS 2024: On-line July to September, 2024
The International Workshop on Improving Data Quality and Quantity in XAFS Spectroscopy (Q2XAFS2024) will be held online between July to September, 2024.
Q2XAFS, Quality and Quantity for XAS, is a conference/workshop series in which expert users and world leaders in X-ray spectroscopy are invited to present an overview of the latest developments and discuss collaborative efforts in response to arising opportunities/challenges in the field. The latest iteration of the Q2XAFS was run at the Australian Synchrotron, ANSTO, as a satellite of the IUCr Congress 2023 in Melbourne, Australia. Working group activities have started to give recommendations in the International XAFS Conference in 2025 in Chicago, USA.

Announcement regarding XAFS19 (XAFS 2025)
2025-07-14 - 2025-07-19
Cancellation of the 19th International XAFS conference in 2025 in Chicago
Dear all involved with XAFS,
As you may know, the 19th International XAFS conference (XAFS 19) was scheduled to occur in Chicago from the 14th to the 19th of July 2025.
After considering the many uncertainties with hosting an international conference in the US given the current political climate, the organizer of the 19-XAFS conference proposed its postponement. The IXAS EC voted on the subject and unanimously voted to cancel the 19-XAFS in Chicago in 2025. We appreciate your kind understanding.
We will now call for a bid to host the conference next year, XAFS 2026, and we will decide on the new venue and communicate the decision to the community as soon as possible. Please contact the IXAS chair, Kiyotaka Asakura (kytkaskr@fc.ritsumei.ac.jp), if you are interested in organizing the XAFS 2026.
The deadline of the bid paper submission is 23:59 JST on 22 April.
Thanks.
Kiyotaka Asakura IXAS Chair
Carlo Segre Chair of the 19-XAFS
