X-ray radiography and tomography of large artworks

Among the activities carried out in Torino related to archaeometry, diagnostics and conservation of Cultural Heritage, the neu ART regional project (collaboration among INFN-Torino, Physics Department of the University of Torino and the Center for Conservation and Restoration La Venaria Reale) developed a system to perform X-ray radiography and tomography of large artworks. The system, based on a linear detector, was designed to help restorers in their work: in fact it allows to obtain information about the state of conservation, the constructive technique, previous interventions, etc. The performance of the system and some case studies will be presented.
