Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

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.
