Macro X-ray fluorescence (MA-XRF) scanning is a well-established imaging technique allowing to visualize the distribution of chemical elements at and below the surface of paintings. Starting from the first experiment in 2008 performed with synchrotron radiation, MA-XRF has been optimized and translated in mobile instruments to be used in museums, archeological sites and conservation studio. It is now one of the hyperspectral methods for non-invasive analysis that is used by art-historians, art-conservators and scientists. Often, the information on the distribution of pigments it reveals on the macroscopic scale is combined with that obtained from microscopic (X-ray or other) analysis of paint stratigraphies.

This workshop aims to bring together scholars having or seeking to gain experience with MA-XRF scanning and related methods of analysis of works of art. At the meeting, the current applications of MA-XRF will be summarized. The advantages and limitations of using MA-XRF and comparable methods of hyperspectral analysis in combination with micro-analytical investigations will be a focal point of the discussions.

The program is now available!

TUTORIAL DAY (under programming)

A tutorial day on MA-XRF with no additional costs for participants to the MA-XRF workshop is under programming for Sunday 24 September 2017. A number of tutorial lectures, demonstrations and hands-on activities related to processing of MA-XRF Datasets will take place at the International Centre for Theoretical Physics (ICTP), Trieste.

Topics to be addressed in the tutorial lectures/hands-on activities include:

- X-ray physics relevant for a better understanding of MA-XRF (e.g. XRF sampling depth, XRF emission lines, X-ray absorption)
- Evaluation of large XRF spectral data sets using tools such as PyMCA and other packages
- Stitching of multiple MA-XRF maps and exploiting inter-element correlation graphs
- Combining MA-XRF with other hyperspectral data sets

Tutors will include: A. Karydas (Democritos, Athens), R. Tagle (Bruker, Berlin), P. Van Espen (University of Antwerp), M. Alfeld (UPMC, Paris), J. Delaney (NGA, Washington DC)
