Abstract: | The paper presents results of recent experiments, as performed with the PF-1000 and PF-6 Plasma-Focus facilities, which were
aimed at investigation of the correlation between processes of the irradiation of different materials of fusion devices and
results of this irradiation. Among the irradiated samples there were pure tungsten, tantalum, copper, aluminum, and alloys,
based on these metals, various steels, carbon and carbon-based materials, which are designed for plasma facing components
or constructional parts of future thermonuclear reactors of the inertial- and magnetic-confinement types. The corpuscular
radiation consisted of high-energy (E
D>100 keV) deuterium ion beams and fast (v
str ≥ 107 cm/s) deuterium-plasma streams. They were investigated by a number of methods with spatial and temporal resolution. Particular
attention was paid to the verification of diagnostic techniques, which might be used for time- and space-resolved studies
of the interaction process. Correlation of these data with information obtained from subsequent analytical investigation of
some of the irradiated specimens, as performed by means of a number of methods typical for material sciences, gives possibility
to deduce physical mechanisms of the deuterium implantation and radiation damage of the investigated materials in dependence
on the conditions of their irradiation. |
