    Simultaneous characterization of O, C, 6Li, and medium-weight impurities concentration in PbLi by ion beam analysis by G. de la Cuerda-Velázquez, G. García, N. Maldonado, E. Carella, R. Gonzalez-Arrabal

    Published 2025-09-01
    “…For a proper reactor operation and control, the exact knowledge of PbLi composition, including impurities and 6Li isotope concentration is required, since it notably influences its properties (corrosion action, T production capabilities and T solubility, among others).Here, we show the capabilities of ion beam analysis (IBA) techniques to accurately determine both of these issues. To do that, we combine nuclear reaction analysis (NRA) and particle induced X-ray emission (PIXE) to quantitatively characterize the C and O concentrations, the isotopic concentration of 6Li, and the medium weight impurities concentration for commercial PbLi samples after exposure to environmental conditions for different times (0.5–15000 h).…”
