Diamond Light Source, Oxfordshire, UK

Diamond Light Source held a workshop on the processing and analysis of XAS data from the 7th-9th of June. Diamond has three x-ray absorption spectroscopy beamlines, one of which is operational, I18, with the other two, B18 and I20, coming online in the first half of 2010. The workshop was aimed at new, existing and potential users of the Diamond spectroscopy beamlines who want to get the most from the data they collect at Diamond.

The workshop was held at Diamond and consisted of a mixture of lectures and hands-on sessions and the course focussed on the use of the IFEFFIT suite of programs in particular the use of Athena and Artemis to perform data processing and analysis.

Topics covered:

  • Overview of a XAFS experiment
  • Basic processing: Background subtraction methods
    Merging data
    Fourier Transforms, K-weighting etc.
  • Data modelling using Artemis
    Constructing a model
    Fitting Parameters
    Evaluating the fit
  • XANES Linear combination fitting

Computing resources for the data analysis sessions were provided by Diamond Light Source. A tour of the Diamond spectroscopy beamlines was also organized, allowing participants to take a close look at the experimental facilities available.

The course was limited to 20 people chosen based on their experience and the relevance of the workshop to their research.
