Abstract
At the research reactor Geesthacht FRG-1, a new neutron tomography station is planned by the GKSS-Research Center. The neutron radiography facility GENRA-3 will be extended to investigate samples up to 40 cm in diameter. Furthermore, in cooperation with the Deutsches Elektronen-Synchrotron DESY, the GKSS-Research Center is building the new synchrotron radiation beamline HARWI-2 at the DORIS storage ring. High-energy X-rays in the range of 20-200 keV will be used to perform X-ray microtomography on small and large samples of up to 10 cm in diameter. Here the different tomographic stations, operated by the GKSS, will be described. The combination of neutron and synchrotron radiation techniques will give new insights into the three-dimensional behavior of samples in materials science
