摘要

The kinetic description of the resonance ripple diffusion of fast ions in tokamaks with toroidal field ripples is presented for the general case of arbitrary toroidal field ripple magnitudes. The topology of banana orbits in phase space is considered. The transport coefficients of 4D Fokker-Planck equations are derived. The algorithms of averaging procedure through superbanana motion are discussed.
