متن کاملEnergetic Particle Mode Dynamics in Tokamaks
Energetic Particle Modes [1] (EPM) are strongly driven oscillations excited via wave-particle resonant interactions at the characteristic frequencies of the energetic ions [1, 2], ωtE, ωBE and/or ωdE , i.e., respectively the transit frequency for circulating particles and the bounce and precessional drift frequencies for trapped ions. A sharp transition in the plasma stability at the critical E...
متن کاملAlfven Cyclotron Instability and Ion Cyclotron Emission
Two-dimensional solutions of compressional Alfven eigenmodes (CAE) are studied in the cold plasma approximation. For finite inverse aspect ratio tokamak plasmas the two-dimensional eigenmode envelope is localized at the low magnetic field side with the radial and poloidal localization on the order of u / f i and u/*, respectively, where rn is the dominant poloidal mode number. Charged fusion pr...
متن کاملRadial Localization of Alfven Eigenmodes and Zonal Field Generation
GTC gyrokinetic particle simulations of DIII-D discharge #142111 near 525ms find a radial localization of toroidal Alfven eigenmode (TAE) due to the modification of the MHD mode structure, i.e., nonperturbative contribution by energetic particles (EP). The EP-driven TAE has a radial mode width much smaller than that predicted by the MHD theory. The TAE radial position peaks at and moves with th...
