“…This can be expected due to the very small energy deposition of neutrons close to the surface. Furthermore, very limited impact of damage on physical sputtering of ions is observed during plasma exposure of high energy ion irradiated tungsten to low temperature plasmas in the linear plasma device LENTA [145]. In these experiments, tungsten samples have been irradiated with 3 MeV helium ions up to damage levels of about 80 dpa before plasma exposure.…”

“…1, 4), плазменные эксперименты проводились методом последовательной экспозиции в режиме динамической эрозии, что позволило исследовать изменения структуры материала по глубине повреждённого слоя и их связь с уровнем повреждения с учётом сильной неоднородности распределения дефектов. Эрозия материала в результате экспозиции на каждом этапе составляла от 0,5 до 1,5 мкм [7,15].…”

“…Irradiation of the material with ions at MeV-energies is performed to obtain damage, and then the irradiated samples are exposed to steady-state plasma. In the first stage, carbon based materials irradiated by C-ions were studied; an enhanced erosion was found in deuterium plasma for the materials damaged to 1-10 dpa [5][6][7]. The further work has been focused on tungsten, and the majority of the results was obtained on tungsten irradiated with 3.5-4.0 MeV He-ions (corresponding to the alphas generated in DT fusion reaction) [8,9].…”
