Effects of circulating energetic ions on sawtooth oscillations

Wang, S.; Ozeki, Takahisa; Tobita, Kenji

Physical Review Letters, 88(10), p.105004_1 - 105004_4, 2002/03

A theoretical model has been established to show that energetic co-circulating ions can stabilize internal kink modes.And the theoretical model has been applied to interpret the recent experiments on sawtooth stabilization by energetic co-circulating ions.

Energetic particles in spherical torus

Tobita, Kenji

Denki Gakkai Kenkyukai Shiryo, Pulazuma Kenkyukai (PST-01-73), p.43 - 46, 2001/09

Behavior of energetic particles in spherical torus (ST) is summarized in comparison with that in tokamaks. The issues treated in this article are neoclassical transport, ripple loss, Alfven eigenmodes and Magetohydrodynamic- instability-induced anomalous transport. ST is expected to be favorable in terms of neoclassical transport and ripple loss. On the other hand, Alfven eigenmodes and the resulting energetic particle loss can be serious concerns in a ST reactor because of a high volume-averaged beta and a super-Alfvenic speed of alpha particles.
