dc.description.abstract© 2019 Elsevier B.V. This paper describes experimental techniques for irradiation of fusion reactor materials with MeV energy ions. The studies were conducted at the NRC “Kurchatov Institute” – ITEP. Two MeV-range linear ion accelerators were used for sample irradiation: the Heavy Ion Prototype (HIPr) accelerator with heavy ions and I-2 accelerator with protons. Target chambers of HIPr accelerator were modified to provide the simultaneous irradiation of four 10 × 10 mm 2 samples at controlled elevated temperatures. Damage rates and profiles were calculated using the SRIM code. HIPr accelerator provided the damage of tungsten samples with 5.6 MeV Fe 2+ ions at a rate of 0.05 dpa/h. I-2 accelerator was used to irradiate tungsten samples with 22 MeV protons to create a uniform damage profile at a depth of 0–400 μm with a rate of 5 × 10 −7 dpa/h. Irradiation of tungsten samples with high energy protons causes generation of 183 Re and 184 Re with a half-life period of 70 and 38 days, respectively. Thus, the samples irradiated with a proton fluence of up to 10 20 protons/m 2 are subject to one year aging before manual handling.
