Time- and Space-Resolved X-ray Absorption Spectroscopy (XAS) at SSRL: Analysis of Large Data Sets

Monday, June 3, 2019 - 8:00am to Tuesday, June 4, 2019 - 5:00pm

A short course sponsored by Co-ACCESS at SSRL

As SSRL transitions from step-scanning XAS to continuous scanning and quick scanning (QEXAFS), time resolution will improve from 10 minutes per spectrum to below 1 second, meaning that the number of spectra that will need to be analyzed will increase dramatically. A similar situation already exists with space-resolved data in X-ray microscopy where thousands and sometimes even millions of spectra need to be processed. With these new parameters, we need appropriate software to process these data batches and extract time- and space-resolved chemical information. This course will present examples of large XAS data sets and solutions for their batch processing, including hands-on exercises. The future in correlated data collection and analysis will also be discussed.
