Распределение водорода и дейтерия в сборке из двух W фольг после воздействия импульсной дейтериевой высокотемпературной плазмы
Samples in the form of assembly is pressed firmly against the two W-foil (230 microns), rolled and sintered powder were irradiated 10th pulses vysokotempera deuterium-temperature 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 the exposure conditions N + - plasma and posleradiatsionnyh investi--ments are described in [1, 2]. It performs measurements of the neutron yield from W foils. Made SEM analysis of the structure and elemental composition of the surface of the irradiated foils W. Conducted RBS and ERD study of foil on both sides showed that deuterium ions under the influence of shock waves knocked out of the first W-foil and penetrate into the second W-foil, 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 describes the observed effects of the first knockout deuterium implanted deuterium W foil and redistribution of hydrogen is discussed.
