摘要: This paper explains, with the example of a Roman object (the ‘Mars from Oberweningen’, Switzerland), why neutrons can be used preferentially for non-destructive analysis metallic objects relatively large size. method is superior to conventional X-ray tomography due higher penetration ability in metals such as copper, tin and even lead. With this method, differing materials also easily differentiated. In way, inner outer structures observed help tools based on mathematical algorithms. Slices at arbitrary positions segmentation different material clusters aid understanding manufacturing processes describe present preservation status. helps selecting optimal additional conservation measures museums further preservation. Beside qualitative overview structure properties objects, quantitative information derived about content composition. subsequently needed facilities are available PSI similar studies demand. arcm_480 272..285
