LABEC, the INFN-university of florence laboratory of nuclear techniques (IBA and AMS) for environment and cultural heritage — •Franco Lucarelli — Department of Physics and Astronomy and INFN, Firenze, Italy

The LABEC laboratory, located in the Scientific and Technological Campus of the University of Florence, is the joint INFN-University of Florence laboratory of nuclear techniques (mainly Ion Beam Analysis (IBA) and Accelerator Mass Spectrometry (AMS)) for environment and cultural heritage. Although those techniques are well-established, a strong effort is put on their upgrade, making them suitable for more and more applications. The laboratory is based on a 3 MV Tandetron accelerator. There are many beam lines; in particular one is devoted to IBA application to Cultural Heritage, one to IBA applications for the study of atmospheric aerosol composition, one to AMS applications, mainly 14C dating with the graphite sample masses down to a few tens of μg of carbon (also for modern art objects). Switching between IBA and AMS operation is very easy and fast, which gives high flexibility in programming the activities. The facilities presently available at the LABEC laboratory, their technical features and some success stories of recent applications will be presented.
