  • Analysis of evolution of gamma-ray emission induced by MeV ions in JET
    Yavorskij, V. ...
    The paper investigates the temporal evolution of gamma-ray emission induced bynuclear reactions between energetic D-T fusion-born alpha particles with beryllium impurity ions in JET plasmas, ... Be-9(alpha, n gamma)C-12. During and after tritium NBI blips into JET deuterium plasmas there occurs a delay between alpha production and gamma-emission. The delay time observed renders possible the assessment of alpha transport, e. g. loss rates of alphas, and hence may be used for fast ion diagnostics if the characteristic confinement time does not exceed similar to 20% of the Spitzer slowing-down time. The analysis of the measured relaxation of gamma-emission is further demonstrated for examining the energy distributions of ICRH accelerated He-4 ions in the MeV energy range.
