dc.description.abstract | During development of a high-performance hybrid scenario for future deuteriumtritium experiments on the Joint European Torus, an increased level of fast ion losses in the
MeV energy range was observed during the instability of high-frequency n=1 fishbones. The
fishbones are excited during deuterium neutral beam injection combined with ion cyclotron
heating. The frequency range of the fishbones, 10 – 25 kHz, indicates that they are driven by
a resonant interaction with the NBI-produced D beam ions in the energy range ≤120 keV.
The fast particle losses in a much higher energy range are measured with a fast ion loss
detector, and the data show an expulsion of deuterium plasma fusion products, 1 MeV tritons
and 3 MeV protons, during the fishbone bursts. An MHD mode analysis with the MISHKA
code combined with the nonlinear wave-particle interaction code HAGIS shows that the loss
of toroidal symmetry caused by the n=1 fishbones affects strongly the confinement of nonresonant high energy fusion-born tritons and protons by perturbing their orbits and expelling
them. This modelling is in a good agreement with the experimental data. | es |
