چکیده
• The analytical derivation of the moment enslavement scheme with good convergence. Successful application to 1D shear Alfvén wave in a broad range β / m e . development mixed particle-in-cell-particle-in-Fourier torus. Simulations toroid eigenmodes using widely studied ITPA case. In this work, an implicit for particle-in-cell/Fourier electromagnetic simulations is developed and applied studies waves one dimension three dimensional tokamak plasmas. An treatment introduced achieve efficient convergence iterative solution field-particle system. First, its one-dimensional uniform plasma demonstrates applicability values. Second, toroidicity induced (TAE) are simulated axisymmetric plasma, case defined by International Tokamak Physics Activity (ITPA) Energetic Particle (EP) Topical Group. real frequency growth (or damping) rate TAE without) EPs agree previous results reasonably well. full f particle established work provides possible natural choice EP transport where large profile variation arbitrary distribution functions need be treated kinetic simulations.

Particle acceleration by electromagnetic waves.
We consider the symmetry in the interaction of photons and electrons, which has led to a common description of electron and photon accelerations; effects such as photon Landau damping arise naturally from such a treatment. Intense electromagnetic waves can act as a photon mirror to charged particles. The subsequent acceleration is equivalent to the photon pulse accelerating electrons. During th...
