Research Activity

 

Giulia Festa is an experimental physicist. Her research interests relate to the development of neutron instrumentation for applications on materials and, in particular, applied to the study of  materials of archaeological and cultural interest.

With regard to neutron instrumentation, GF worked on the development of neutron imaging instrumentation (Prompt Gamma Activation Imaging) and devices for gamma and neutron detection (Silicon Photo-Multiplier technology,  neutron radiative capture-based counting technique). Within the EU-funded ANCIENT CHARM project, GF developed ancillary equipment and gamma detectors to be used for Neutron Resonance Capture Imaging (NRCI) and neutron tomography on objects of cultural and archaeological interest as well as software for data analysis.

GF employed scientific investigation techniques in the field of archaeological research providing successful results such as the integrated neutron analysis of the Ghiberti East Door from the Florence Baptistery determining state of conservation and manufacturing technique, or the study about the composition and corrosion products of Etruscan Bronzes from the Museo Nazionale di Villa Giulia.
