SRμCT in Materials Science at the Beamline HARWI II — •Julia Herzen, Felix Beckmann, Astrid Haibel, Tilman Donath, Funda S. Bayraktar, Stefan Riekehr, Mustafa Kocak, and Andreas Schreyer — GKSS Research Centre, Max-Planck-Str.1, 21502 Geesthacht

The synchrotron radiation based micro tomography is a powerful imaging tool in the wide range of materials science. Compared to laboratory X-ray sources the micro tomography at a synchrotron allows to visualize non-destructively high and low absorbing materials without any beam hardening effect and with a very high density resolution.

The beamline HARWI II operated by the GKSS Research Centre in cooperation with Deutsches Elektronen-Synchrotron DESY, Hamburg is designed for materials science experiments using hard X-rays. A fixed-exit monochromator provides a highly intense, monochromatic X-ray beam in the energy range between 15 and 200 keV. This large range of photon energies, the spatial resolution down to 3 μm and the high density resolution are important for microtomographic applications. The advantages of the beamline are demonstrated for absorption contrast tomography study of crack propagation within laser welded Al-Alloy T-Joints.
