Workshop on Advances in XAFS Experimental Techniques: Bridging The Light Source Generations

Scope

Currently, we are witnessing the emergence of a new chapter of the history of x-ray light sources, i.e., the 4th generation light sources (4th GEN LSs) which embrace both XFELs and ultra-low emittance synchrotron radiation storage rings owing to a novel multi-bend achromat (MBA) lattice design started from MAXIV. It is anticipated that XAFS research will take a leap forward by these advanced LSs, greatly improving experimental limitations and opportunities of new experiments such as coherent x-ray spectroscopy.

Although fundamental XAFS techniques remain unchanged, it is also required that some critical issues should be overcome before exploiting the full potential of the advanced LSs. In this workshop, experimental challenges and scientific opportunities of the 4th GEN LSs will be discussed by experts. The workshop program is planned to “bridge the different generations” of experimental facilities and instrumentations, which would allow researchers to understand the capabilities of the 4th GEN LSs and get ready for entering into the new scientific opportunities beyond the present limitations.

Invited talk slot includes a discussion time. A panel discussion is devoted to a summary discussion on scientific opportunities of the 4th GEN LSs.

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.

Hands-on workshop on spectroscopy with FEFF and DFT

This hands on workshop will focus on using FEFF9 to simulate XANES and related spectroscopies. We will begin by instructing participants on the use of FEFF9 with the JFEFF GUI, from installation, to simple examples and tips. Participants will follow along on their own laptop. We will also talk about the combined use of DFT and FEFF to obtain more accurate calculated results and improved physical interpretation of data. Finally, if time permits, we will help participants in simulating XAS of some physical system of interest to them.

 

Requirements:

  1. Laptop: Most reasonably modern laptops will work.
  2. WINDOWS and LINUX users: Current version of Java JRE installed. You can download at https://java.com/en/download/
  3. MAC OSX users: Current version of Java JDK installed. You can download at
    http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
  4. Please bring a system from your own research, for which you would like to simulate a spectrum.
