Ion Beam Analysis and Modification

The group investigates the interaction of energetic particles with fusion-relevant materials.

The group operates the tandem accelerator laboratory for quantitative ion beam analysis. Dedicated samples from basic laboratory experiments as well as components of the fusion experiments AUG, W7-X or JET are examined. An additional important diagnostic is thermal desorption spectroscopy.

Present topics are hydrogen transport and retention in fusion-relevant materials as well as material transport in fusion experiments. Furthermore, crystal lattice damage is created by implanting high-energy ions in materials to simulate the effect of neutron irradiation.
