      abstract     = {In order to estimate the fuel loss in ITER and further
                      future fusion devices, the deuterium permeation through
                      different wall and structural materials are studied. In
                      order to determine the effective permeability, gas-driven
                      deuterium permeation measurements are performed on Cu and
                      ITER grade CuCrZr. The obtained permeabilites for Cu and
                      ITER grade CuCrZr are very similar and in agreement to
                      literature values for Cu. For a better estimation for fusion
                      reactor components, combined material samples are studied.
                      Cu layers were applied on steel substrates by magnetron
                      sputter deposition. With these studies, the influence of
                      interfaces and microstructure on the hydrogen permeation is
                      investigated. Our study reveals that in the case of Cu
                      layered steel substrates the influence of the interface on
                      the permeation flux is minor compared to the influence of
                      the microstructure on the permeability. The Cu layer
                      permeability is around one order of magnitude smaller than
                      the Cu bulk permeability in the temperature range between
                      300 and 550.},
