Virtual SSRL Summer School on Synchrotron X-Ray Absorption Spectroscopy and Imaging Oct 25-28, 2022

Hello EXAFS enthusiasts, We are hosting the SSRL "not quite summer" summer school at the end of October this year (Oct 25-28). We wanted to include real experiments and deferred the school to the start of operations at SSRL. The event is virtual and all information (including registration details) can be found at: https://conf.slac.stanford.edu/exafs-2022/ We recognize that there are several really good online resources for learning about EXAFS and it has proved to be quite beneficial to the new and experienced learners alike. We have changed our summer school format to include additional teaching modules that can help participants learn aspects of EXAFS data analysis that are beyond what we have typically taught in the past. These new modules are especially helpful to the novice user and include: 1) Opportunity to write a 1 to 1.5 page proposal to compete for experimental time during the school. 2) A complete 1-day remote data measurement and hands-on demonstration of beamline optimization and experiment setup during the live session. 3) Insights into becoming a user at SSRL, proposal writing and its review process with examples of past successful proposals. Looking forward to seeing some of you at the school. Best Regards, Riti Sarangi

XAFS fitting in xas_viewer and reset of customized variables after save & load cycle
by juejing.liu＠gmail.com 04 Sep '22

04 Sep '22

Hi all, I am using xas_viewer, version 0.9.65, to fit some XAFS data. In a typical situation I will also fit the coordination numbers of atoms by add customized variables in the amplitude boxes (image below). It works fine during my fitting. However, when I save my result as a larch session and load it later, all my customized parameters are disappeared, and the amplitude boxes are reset. Therefore, I need to refill all the variables after each save & load cycle. This becomes increasingly tedious when dealing with about 20 different paths. Is there any workaround of this problem?
