Accelerators in Art and Archaeology: The Analytical Facility of the Louvre

Joseph Salomon, CNRS, FRANCE
Building 6008, Conference Room

A large set of modern analytical techniques is currently applied to get a better insight into art and archaeological objects as well as to contribute to their conservation and restoration. Because of the precious and sometimes unique character of the works, non-destructive techniques and even those requiring no (or only minute) sampling, are preferred. >From this standpoint, ion beam analysis (IBA) constitutes one of the best choices, since it combines quite good analytical performance and non-destructiveness. For almost 14 years, an IBA facility has been installed in the Research Laboratory of the Museums of France. Until now it is the only facility of this kind entirely devoted to the study of cultural heritage. A special set-up, namely an external beam line, has been developed which permits the in-air analysis of large or fragile works of art without sampling. This facility is used for both short investigations, at the request of museum curator and extensive research work in art history and archaeology. Numerous examples, will be given to highlight the impact of this tool. A second facility dedicated to14C dating by accelerator mass spectrometry is under construction and will be operational in early 2003. It will be shared with other scientific communities and used about half time for dating art and archaeological objects.
