Microturbulence driven transport of energetic ions in the ITER steady-state scenario
2010
Modelling of microturbulence-driven transport of energetic ions in an ITER steady-state scenario is presented. Results indicate that a significant fraction of the velocity space distribution of alpha particles and deuterium ions can be transported above neoclassical predictions. Turbulent magnetic fluctuations are found to significantly enhance the fast ion diffusivity. Overall, the conclusion that turbulent fields have a limited influence on the transport of fusion born alpha particles is drawn. At the same time, anomalous fast ion diffusion could have an impact on the neutral beam driven current in ITER.
