Workshop on Analysis of Synchrotron Based X-ray Fluorescence Images for Ancient Materials and Beyond by Samuel Webb

par Bénédicte Charbonnel - publié le , mis à jour le

On the 12th of October 2018 Dr Samuel Webb, staff scientist at SLAC National Accelerator Laboratory – Stanford Synchrotron Radiation Lights Sources (United-States), will organize a workshop on the Analysis of Synchrotron Based X-ray Fluorescence Images for Ancient Materials and Beyond from 10:00 AM to 5:00 PM at IPANEMA.

This one-day workshop will introduce a series of analysis strategies for synchrotron based x-ray fluorescence (XRF) imaging and x-ray absorption spectroscopy (XAS). Synchrotron XRF provides spatially resolved information on the elemental composition, which can be complemented by XAS in order to determine the specific chemistry of elements of interest. The principles behind each technique can be combined in a sparse excitation energy x-ray absorption spectroscopy (seeXAS) technique that gives a spatially resolved chemical composition image map.

The morning will focus on the principles behind the techniques, and data collection strategies. The afternoon will build on data analysis, using several different types of example cases as data sets as well as at the end, examine data sets from the participants. Students will take away a working knowledge of seeXAS imaging techniques and various methods of analysis for XRF imaging, as well as how to use these processes at the beam line in real time in order to optimize data.

Samuel Webb is hosted at IPANEMA thanks to a Jean d’Alembert grant of Université Paris-Saclay.
This programme enables highly qualified young researchers and senior scientists to make stays of long duration (6 to 12 months) in one of the laboratories of the perimeter of the University.
