    We describe a new technique for the efficient generation of high-energy ions with electromagnetic ion cyclotron waves in multi-ion plasmas. The discussed ‘three-ion’ scenarios are especially suited for strong wave absorption ...

  • ICRH physics and technology achievements in JET-ILW 

    Jacquet, P.; van Eester, D.; Lerche, E.; Bobkov, V.; Blackman, T.; Colas, L.; Challis, C.; Czarnecka, A.; Dumortier, P.; Frigione, D.; Durodié, F.; Garzotti, L.; Goniche, M.; Graves, J.; Kazakov, Y.; Kirov, K.; Klepper, C.C.; Krawczyk, N.; Krivska, A.; Mantsinen, Mervi; Monakhov, I.; Nunes, I.; Ongena, J.; Reinke, M.; Rimini, F.; Zhang, W.; JET Contributors (EDP Sciences, 2017-10-23)

    ICRH was extensively used in the 2015-16 JET-ILW (ITER like wall) experimental campaign; bulk heating together with high-Z impurity chase-out from plasma centre importantly contributed to the good DD fusion performance ...

  • Synergetic heating of D-NBI ions in the vicinity of the mode conversion layer in H-D plasmas in JET with the ITER like wall 

    Ongena, J.; Kazakov, Ye O.; Baranov, Y.; Hellesen, C.; Eriksson, J.; Johnson, T.; Kiptily, V.G.; Mantsinen, Mervi J.; Nocente, M.; Bilato, R.; Cardinali, A.; Castaldo, C.; Crombé, K.; Czarnecka, A.; Dumont, R.; Faustin, J.; Giacomelli, L.; Goloborodko, V.; Graves, J.; Jacquet, Ph.; Krawczyk, N.; Lerche, E.; Meneses, L.; Nave, M.F.F.; Patten, H.; Schneider, M.; Van Eester, D.; Weisen, H.; Wright, J.C.; JET Contributors (EDP Sciences: EPJ Open Access, 2017-10-23)

    This paper discusses the extension of the ‘three-ion’ species ICRF technique for heating mixture plasmas using fast injected NBI ions as resonant ‘third’ species. In this scenario the ICRF power is absorbed by the fast ...
