CEDAD - CEnter of Applied Physics, DAting and Diagnostics – is a research Center at the University of Salento established 15 years ago in the framework of a Coordinated Plan between the University of Catania and Lecce. The main goal of the project was to realize the first Italian Center for research and service for radiocarbon dating by Accelerator Mass Spectrometry (AMS). Over the years at CEDAD the 3 MV Tandetron accelerator has been continuously upgraded so that six beamlines and four ion sources have been designed and connected to the accelerator. CEDAD is nowadays a multidisciplinary facility for environmental, archaeological, geological and materials science studies with nuclear techniques such as AMS, RBS/Channeling, PIXEPIGE, Ion Implantation, and Nuclear microbeam. Recently a new AMS beamline for rare isotopes other than 14C has been designed in collaboration with the Ion Beam Physics group at ETH in Zurich for the detection of rare isotopes such as 10Be, 26Al, 129I and uranium isotopes. In addition a new gas ion source for measuring 14C samples with masses less than 10 μg has been installed. The research activities will be mainly in the fields of Earth, Marine sciences and nuclear safeguards. In this seminar a brief history of the CEDAD and the AMS technique will be presented and the SIDART, BLU-ARCHEOSYS, IT@CHA, DICET and BOLAS projects will be described. It will be shown the potentialities of the integrated approach of the IBA and AMS techniques for performing with the same accelerator studies in many research fields. Moreover in the field of environmental monitoring an overview will be presented of research carried at CEDAD for monitoring the anthropogenic carbon dioxide emissions into the atmosphere and for the quantification of the biogenic fraction in carbon based products (plastics, resins, bio-fuels) and in industrial atmospheric emission such as flue gas from WTE (Waste to Energy Plants).
