Abstract	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 iron or aluminium-walled cubes of 40 and 50 mm edge lengths, respectively, 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 experimental results obtained from PGAI on boxes investigated at Budapest Neutron Centre (BNC, Hungary) are reported. Kivonat Az EU FP6 Ancient Charm projekt fő celkitűzese osszetett, ertekes műtargyak elemeloszlasanak, fazisszerkezetenek haromdimenzios, roncsolasmentes felterkepezese neutronos analitikai modszerek kombinalasaval: neutrontomografia (NT), prompt-gamma aktivacios analizis (PGAA), repulesiidő neutrondiffrakcio, neutron-rezonanciabefogas analizis (NRCA) es neutron-rezonanciatranszmisszio (NRT). A kombinalt modszerek fejlesztesehez es tesztelesehez un. fekete dobozok keszultek, amelyek vas ill. aluminium falu probatestek, belsejukben regeszeti szempontbol fontosnak tartott anyagok komplex elrendezesevel. A prompt-gamma aktivacios lekepezes (PGAI) egy uj terminologia; olyan 3D-s elemosszetetel vizsgalatot jelent, amelynek soran keskeny neutronnyalabbal a minta kis terfogategysegeit lepesenkent elemezzuk. Jelen cikk a Budapesti Neutron Centrumban a fekete dobozokon vegzett PGAI vizsgalatok eredmenyeit mutatja be.
