Workshop on Advances in XAFS Experimental Techniques: Bridging The Generations

Scope

 

Currently, we are witnessing the emergence of a new chapter in SR history, i.e., the 4th generation light sources (4th GEN LSs) which embrace both XFELs and low emittance synchrotron radiation storage rings (LSRs), the latter having started with a novel multi-bend achromat (MBA) lattice at MAXIV. We anticipate that XAFS capabilities will take a leap forward by these 4th GEN LSs, allowing drastic improvements in terms of spectroscopic limitations in energy, space and/or time, but also relaxing sample requirements in volume and concentration.

 

Although fundamental XAFS techniques remain unchanged, there are some critical issues to address before exploiting the full potential of these light sources. In this workshop, both scientific feasibility and experimental challenges of the 4th GEN LSs are intensively discussed by experts to find solutions to experimental challenges. The workshop is planned to “bridge the different generations” of experimental facilities, allowing researchers to go beyond the present capabilities and enter new scientific opportunities. Each lecture is followed by 15min. hands-on data analysis on a typical experimental data.

An Introduction to XAFS Data Analysis with Athena and Artemis

This one-day session will provide an overview of the use of the Demeter package, including Athena (XAFS data reduction and processing) and Artemis (EXAFS data analysis), for real-world analysis problems in materials science, environmental science, chemistry and energy science, and other fields. This course presumes a basic knowledge of the science and measurement of X-ray absorption spectroscopy. With live demonstrations and ample hands-on time, the participants will learn how to apply these analysis tools to their own research interests.

 

The software is freely available at http://bruceravel.github.io/demeter/ and should be downloaded and installed prior to the course.
