Radiográfiával kombinált prompt-gamma aktivációs analízis és neutron diffrakciós mérések az Ancient Charm projekt számára tervezett fekete dobozokon

The aim of the ‘Ancient Charm’ project is to combine Neutron Tomography (NT), Prompt Gamma Activation Analysis (PGAA), Time-of-flight Neutron Diffraction (TOF-ND), Neutron Resonance Capture Analysis (NRCA) and Neutron Resonance Transmission (NRT) in order to generate 3D images of the elemental and phase compositions of complex museum objects. For the development and benchmark of the combined methods, complex test samples, so called ‘black boxes’, were constructed and then analysed by the different techniques. These test objects are sealed cubes, containing 2D or 3D arrangements of materials relevant to the compositions of archaeological samples. The Prompt Gamma Activation Imaging (PGAI) is a new terminology – introduced in the AC project – for determining the compositions of small volumes within the sample by scanning. The presented experimental results are obtained from PGAI and TOF-ND investigations.
