Description
Most widespread element analysis techniques are not suitable for bulky heterogeneous or structured objects. Prompt-gamma activation imaging (PGAI), in combination with neutron tomography (NT), has proven its potential to fill this niche, thanks to the non-destructive nature and the high penetration depth of neutrons and gammas. This is of utmost importance for valuable cultural heritage objects. Following the success of the demonstration measurements within the ANCIENT CHARM EU FP7 NEST project, NIPS-NORMA, the single operational facility for this purpose worldwide, was set up in 2012 at the Budapest Neutron Centre.
Neutron imaging and local chemical compositions from PGAI-NT technique can be combined even with high-definition X-ray imaging, or a laser-scanned point cloud, in order to achieve a comprehensive characterization of macroscale structure and the in-depth, but still localized elemental composition. Detailed computer simulations can be used to derive corrections for self-absorption and self-shielding. The joint interpretation of these so-far separately treated datasets offers significant benefits.
