Influence of sawtooth oscillations on fast ions in a stellarator
Sawtooth oscillations in tokamaks frequently lead to the redistribution of energetic ions, mainly on passing orbits, causing their expulsion from the core. This paper discusses the first measurements of the interaction of fast ions and sawteeth in the Large Helical Device (LHD). The crashes, caused by changed rotational transform profile due to electron cyclotron current drive (ECCD) and neutral beam current drive (NBCD), show no redistribution effect on fast ions in the core or at the edge.
