Teaching content

Students have researching topics about analytical techniques and control methods of hydrogen isotopes as fuel sources in the fusion reactors, such as 1)Wall conditioning methods on plasma-facing materials in ITER and DEMO, 2) Quantitative analyses of retained hydrogen isotopes in the fusion reactor with the remote handling environment, and 3) the relationship between irradiation damages by plasma exposures and hydrogen isotopes on the walls. In addition, support for researching experiences in another institute/university can be obtained.
