A possibility to use experimental observations of low-frequency plasma instabilities for plasma diagnostics is demonstrated. The structure of ideal TAE-modes is studied with using the ballooning formalism. The effect of toroidal field ripple on the confinement of injected deuterons and charged DD fusion products is investigated. The effect of the ripple on the velocity of plasma rotation in JET is investigated. The physical mechanisms responsible for the stabilization of sawtooth oscillations by circulating energetic ions are investigated. The influence of the spatial inhomogeneity the magnetic field, the non-dominance of its mirror harmonic, the plasma pressure, and the electric field on the stochastic diffusion of fast ions in stellarators is studied. New expressions for the coefficients of this diffusion are derived.
