Abstract
For the performance assessment of fusion reactor solid breeder materials, the production behavior of irradiation defects in some candidate materials of Li 2TiO 3, Li 2ZrO 3 and Li 2SnO 3 was studied by an in situ luminescence measurement technique under ion beam irradiation. The luminescence was observed to be composed of multiple luminescence bands and the temperature dependence of the luminescence intensity was measured under He + or H + ion beam irradiation. The production mechanism of irradiation defects was discussed by comparing the present results with those previously obtained for Li 2O. The effects of irradiation defects on tritium recovery kinetics and material stability were pointed out.
