2022 APS/IIT XAFS Summer School


For more information, and to apply, please email bunker@iit.edu with the subject line “2022 XAFS School”. 


This XAFS summer school is an extended version of the summer school offered previously at IIT in Chicago in collaboration with the Advanced Photon Source. It will again be at IIT in Chicago, in-person (COVID-permitting; bring a mask), and it will run Sunday-Friday, with experiment day at the APS on Tuesday. Course material will cover fundamental and practical aspects of X-ray Absorption Fine Structure Spectroscopy: basics, sample preparation, experiment, theory, data analysis.

One day of hands-on experiments will be carried out by participants at a handful of APS beamlines, followed by a guided data analysis laboratory using Larch/Athena/iFEFFIT family of programs. Several computers will be available for those participants attending without their own laptops, but it’s best to bring your own. The target audience is graduate students, postdocs, and experienced scientists who are new to XAFS and want to use it in their own research. Space is available for up to 40 students.

Instructors include: Matt Newville (UChicago), Shelly Kelly (Honeywell), Bhoopesh Mishra (IIT), Carlo Segre (IIT), Grant Bunker (IIT), Jeff Terry (IIT), and other experienced XAFS researchers.

The cost of the course is $650 USD, which covers most but not all meals via an IIT meal card. Participants will be responsible for their own housing (available on and off IIT campus) and travel to/from their home institutions. IIT is readily accessible by car, cab, and CTA train from O’Hare and Midway airports. Free time will be available most evenings including dinner time for participants to visit Chicago attractions such as Grant Park, the Loop, Millennium Park, Lake Michigan; music, architecture, art, theater; Chinatown, White Sox, Field Museum, Shedd Aquarium, Adler Planetarium, and Navy Pier, and numerous restaurants and pubs. July 24-29, 2022 Illinois Institute of Technology Department of Physics Robert A. Pritzker Science Center 31st and State St. Chicago, IL 60616
