The main attention is paid to the processes connected with energetic ions, which are produced as a result of a thermonuclear reaction, neutral beam injection, and the acceleration during high-frequency plasma heating. A theory of destabilization of Alfven instabilities in stellarator plasmas with energetic ions is developed; numerical modelling of these instabilities in experiments on Wendelstein 7-AS and LHD is carried out; fishbone instability caused by circulating ions is studied; the confinement of energetic ions in tokamaks with hollow current is investigated, in particular, in the JET tokamak ; the nonlinear dynamic of zonal flow near the instability threshold is investigated.
