Ray trajectories of fast magnetoacoustic waves in the lower-hybrid frequency range in tokamaks

D.L. Grekov, V.E. D'Yakov, K.N. Stepanov1983年Nuclear FusionIF 3出版社

The ray trajectories of the fast mode (FM) of magnetoacoustic waves in tokamak plasmas are examined, account being taken of the toroidal displacement of the magnetic surfaces and of other toroidal effects. The peculiarities of the ray trajectories and of wave absorption are analysed. It is shown that FM with frequencies near the lower-hybrid frequency and rather small initial slowing-down can be used both for plasma heating in large tokamaks and for maintaining steady-state current.
