Распределение водорода и дейтерия в сборках из двух Zr, Ti и Ni фольг после воздействия импульсной дейтериевой высокотемпературной плазмы
Samples in the form of an assembly of two tightly pressed Zr (0,3 mm), Ti (0,25 mm) and Ni (0,1 mm) foils were irradiated with 15 pulses high deuterium plasma (up to 10 keV) on the "Plasma focus "(PF-4, FIAN) [1, 2] for the creation of shock waves and deuterium ion implantation. Options PF-4 and deuterium plasma exposure conditions and posleradiatsionnyh studies described in [1, 2]. It performs measurements of the neutron yield from all assemblies foils. Studies of foil on both sides by recording recoil nuclei (ERDA) showed that deuterium ions under the influence of shock waves knocked out of the first foil and penetrate into the second foil of the same composition as initially present in the sample hydrogen redistributed. The measured depth profiles of all distributions and integral concentration of deuterium and hydrogen, both sides of each of the foils are presented. The model describing the observed effects in the first knockout implanted deuterium foil and redistribution of impurities under discussion. SEM studies of changes made and the elemental composition of the surface, the results are discussed.
