    • Analysis of the potential of ICRF waves to heat bulk ions in DEMO 

      Gallart, Daniel; Mantsinen, Mervi; Kazakov, Yevgen (European Physical Society (EPS), 2015)
      Conference report
      Open Access
      While ITER’s main purpose is to confirm the feasibility of nuclear fusion as an energy source, DEMO is planned as the first fusion reactor to produce net electrical energy. Our analysis is carried out for the DEMO 2015 ...
    • Efficient generation of energetic ions in multi-ion plasmas by radio-frequency heating 

      Kazakov, Ye.O.; Ongena, J.; Wright, S.J.; Wukith, S.J.; Lerche, E.; Mantisen, Mervi; van Eester, D.; Craciunescu, T.; Kiptily, V.G.; Lin, Y.; Nocente, M.; Nabais, F.; Nave, M.F.F.; Baranov, Y.; Bielecki, J.; Bilato, R.; Bobkov, V.; Crombé, K.; Czarnecka, A.; Faustin, J.; Felton, R.; Fitzgerald, M.; Gallart, Daniel; Giacomelli, L.; Golfinopoulos, T.; Hubbard, A.; Jacquet, Ph.; Johnson, T.; Lennholm, M.; Loarer, T.; Porkolab, M.; Sharapov, S.; Valcarcel, D.; van Schoor, M.; Weisen, H.; JET Contributors; Alcator C-Mod Team (Nature Publishing Group, 2017-06-19)
      Article
      Open Access
      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 ...
    • Extrapolations of the fusion performance in JET 

      Gallart, Daniel; Mantsinen, M.J.; Garzotti, L.; Challis, C.; Garcia, J.; Gutiérrez, A.; Sáez, X. (Barcelona Supercomputing Center, 2015-05-05)
      Conference report
      Open Access
      n preparation of the forthcoming high power campaign with the reactor-relevant deuterium-tritium (DT) fuel mixture in the Joint European Torus (JET), significant efforts are being devoted to DT scenario extrapolation using ...
    • Modelling of ICRF heating in DEMO with special emphasis on bulk ion heating 

      Gallart, Daniel; Mantsinen, Mervi; Kazakov, Yevgen (AIP, 2015-12-10)
      Conference report
      Open Access
      Ion cyclotron resonance frequency (ICRF) heating is one of the auxiliary heating schemes presently envisaged for ITER and DEMO. In this paper we analyse the potential of ICRF waves to heat the fuel ions in DEMO. Our analysis ...
    • Overview of the JET preparation for deuterium-tritium operation with the ITER like-wall 

      Joffrin, Emmanuel; Abduallev, Sadrilla; Abhangi, Mitul; Futatani, Shimpei; Gallart, Daniel; Gutiérrez, Albert; Mantsinen, Mervi Johanna; Saez Pous, Xavier; Rakha, Allah (2019-11-01)
      Article
      Open Access
      For the past several years, the JET scientific programme (Pamela et al 2007 Fusion Eng. Des.82 590) has been engaged in a multi-campaign effort, including experiments in D, H and T, leading up to 2020 and the first experiments ...
    • Simulations of combined ICRF and NBI heating for high fusion performance in JET 

      Gallart, Daniel; Mantsinen, Mervi; Garzotti, Luca; Bilato, Roberto; Challis, Clive; Garcia, Jerónimo; Gutierrez-Milla, Albert; Johnson, Thomas; Lerche, Ernesto; Sáez, Xavier; van Eester, Dirk (2016-07-08)
      Conference lecture
      Open Access
      We report on simulations aimed at optimizing external heating using neutral beam injection (NBI) and radiofrequency waves in the ion cyclotron range of frequencies (ICRF) for high fusion yield in the JET tokamak. In this ...
    • Third harmonic ICRF heating of Deuterium beam ions on ASDEX Upgrade 

      Mantsinen, Mervi; Bobkov, Volodymyr; Gallart, Daniel; Geiger, Benjamin; Johnson, Thomas; Meyer, Hendrik; Nocente, Massimo; Ochoukov, Roman; Odstrčil, Tomas; Perelli, Enrico; Rasmussen, Jens; Schneider, P. A.; Sharapov, Sergei; Tardini, Giovanni; Tardocchi, Marco; Vallejós, Pablo; ASDEX Upgrade; EUROfusion MST1 (European Physical Society (EPS), 2016-07-08)
      Conference report
      Open Access
      We report on recent experiments on the ASDEX Upgrade (AUG) tokamak (major radius R ≈1.65 m, minor radius a ≈ 0.5 m) with third harmonic ICRF heating of deuterium beam ions. Prior to this work, the ...
