Superpermeability: Critical points for applications in fusion
TL;DR: Theoretical estimates give the maximum fluxes of ∼ 10 19 cm −2 s −1 for the V group metal membranes as mentioned in this paper, which can be easily incorporated into the up-to-date ITER design concept.

Hydrogen superpermeation resistant to ion sputtering
TL;DR: In this paper, it was shown that Nb containing an O impurity would be normally superpermeable to suprathermal hydrogen at any incident energy, whereas the usual sensitivity to sputtering is conditioned by a NbC layer originally present at the real surface of Nb.

TL;DR: A reproducible long-time plasma driven superpermeation was observed at all the flux densities up to 2 x 10 17 H cm -2 s -1 at membrane temperatures, T m, 500-1000°C.

Effect of ion bombardment on plasma-driven superpermeation of hydrogen isotopes through a niobium membrane
TL;DR: In this article, a superpermeable niobium membrane was investigated under bombardment of the input membrane surface with hydrogen, deuterium and helium ions with energy 0 −250 eV over the range of membrane temperature 910 − 1420 K. The membrane surface was covered with a nonmetal monolayer generating a potential barrier responsible for the superpermability to suprathermal hydrogen particles.

Hydrogen superpermeation resistant to ion sputtering
TL;DR: In this article, it was shown that Nb containing O impurity will be normally superpermeable to suprathermal hydrogen at any incident energy, the earlier observed sensitivity to sputtering being conditioned by the NbC layer originally present at the real Nb surface.
