      Eriksson, Johan; Scopus - Author details - Nocente, Massimo; Binda, Federico; Scopus - Author details - Cazzaniga, Carlo; Conroy, Sean W.; Ericsson, Göran N.; Giacomelli, Luca C.; Gorini, Giuseppe; Hellesen, Carl; Hellsten, Törbjrn; Hjalmarsson, Anders; Jacobsen, Arnhild S.; Johnson, Thomas; Kiptily, Vasily; Koskela, Tuomas; Mantsinen, Mervi; Salewski, Mirko; Schneider, Michael; Sharapov, Sergei; Skiba, Mateusz; Tardocchi, Marco; Weiszflog, Matthias (Institute of Physics Publishing (IOP), 2015-11-19)
      Article
      Open Access
      Observations made in a JET experiment aimed at accelerating deuterons to the MeV range by third harmonic radio-frequency (RF) heating coupled into a deuterium beam are reported. Measurements are based on a set of advanced ...

    • 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 ...
