The paper devotes to study of hydrogen and deuterium storage and research of capturing hydrogen and deuterium in tungsten samples irradiated with plasma beam. The paper shows that some changes occur in the surface like relief propagation caused by heterogeneous surface etching after irradiation with hydrogen plasma. Ratio of change in relief and structure of irradiated samples’ surface layer herewith depends on the irradiation temperature. Hydrogen and deuterium storage in tungsten have been studied while their irradiation with hydrogen and deuterium plasma. Thermo-desorption analysis of tungsten samples irradiated with hydrogen and deuterium plasma at 1000°С degrees showed that tungsten surface became saturated with deuterium and did not become saturated with hydrogen. The data obtained by emission spectrometry and thermo-desorption spectrometry verified, that the basic share of captured deuterium is accumulated at the depth of up to 7 µm.Keywords: Tungsten, accumulation, hydrogen, deuterium, plasma, irradiation
