| Summary: | Title screen Nanosecond proton and deuteron bunches collectively accelerated in a portable Luce diode were used for non-destructive radioactivation determination of carbon impurities in ceramic BeO plates using a pair of the 12C(p,γ)13N and 12C(d,n)13N nuclear reactions. The 13N activity induced in the irradiated samples was measured with a Ge detector at the peak of 511 keV annihilation γ-quanta after irradiation of each sample. The 457 keV resonance of the (p,γ) reaction is most sensitive at a depth of 2–5 μm with a detection limit of carbon up to 0.02 wt%, while the (d,n) reaction is most sensitive on the surface of samples, which together makes it possible to estimate the contribution of surface contamination with carbon to the result of carbon determination by the first reaction and to model the possible distribution of carbon in the near-surface layer of any solids. Our analysis showed that at an estimated depth of 0.1–10 μm, the BeO ceramics contained 0.31 wt% carbon Текстовый файл AM_Agreement |
