Brilliant light for materials science: industrial applications of synchrotron radiation-based microtomography at the tomography instruments by GEMS at PETRA III


GEMS is the user platform of Helmholtz-Zentrum Geesthacht with a unique infrastructure for complementary research with photons and neutrons. The instruments using synchrotron radiation are operated at DESY in Hamburg, the instruments using neutrons are located at the research reactor FRM II of the Heinz Maier-Leibnitz Center (MLZ) in Garching near Munich. GEMS provides methods for applied materials research to user groups from both industry and science. At the PETRA III synchrotron storage ring of the German Electron Synchrotron (DESY), GEMS operates instruments for tomographic analyses from the micro- to the nanoscale. The high-energy tomography station of the beamline HEMS/P07 uses photon energies from 50 to 200 keV. A robot sample changer enables automated high-throughput measurements. The beamline is therefore of special interest for industrial users, especially from the metal industry sector. In this contribution we introduce the tomography set-up at HEMS and the possibilities for industrial access, together with examples for tomography of challenging highly-absorbing samples.
