Keywords:Tritium, Permeation, Coating, Erbium oxide, Ion irradiation

Studies on tritium permeation barrier at fusion reactor blankets have been recently developed with erbium oxide coatings. In this presentation, deuterium permeation behaviors for erbium oxide coatings with two crystal structures, cubic and monoclinic, and its irradiation effect will be reported.
