Radial 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...
متن کاملFast-Ion Transport Induced by Alfven Eigenmodes in ASDEX Upgrade
A comprehensive suite of diagnostics has allowed detailed measurements of the AE spatial structure and subsequent fast-ion transport. RSAEs and TAEs have been driven unstable by fast-ions from ICRH as well as NBI origin. In ICRF heated plasmas, diffusive and convective fast-ion losses induced by AEs have been characterized in fast-ion phase-space. While single RSAEs and TAEs eject resonant fast...
متن کاملHigh-ti Stability of Alpha Particle Driven Alfven Eigenmodes
In the present work, we analyse the two dimensional (2-D) mode structures and global stability of the Alfvkn branches, whose frequencies are close to the toroidicity induced A1fv.h continuum gap. The fully 2-D problem is solved using a two spatial-scale WKBJ formalism without employing perturbation theory in treating drive and damping terms. A code that solves the 2-D mode structures and global...
متن کاملMHD Turbulence : Properties of Alfven , Slow and Fast Modes
We summarise basic properties of MHD turbulence. First, MHD turbulence is not so messy as it is believed. In fact, the notion of strong non-linear coupling of compressible and incompressible motions along MHD cascade is not tenable. Alfven, slow and fast modes of MHD turbulence follow their own cascades and exhibit degrees of anisotropy consistent with theoretical expectations. Second, the fast...
متن کاملHybrid magnetohydrodynamic-gyrokinetic simulation of toroidal Alfven modes
Resonant energetic particles play a major role in determining the stability of toroidal Alfven eigemnodes (TAE’s) by yielding the well-known driving mechanism for the instability and by producing an effective dissipation, which removes the singular character of local oscillations of the shear-Al&n continuum and gives discrete kinetic Alfven waves (KAW’s). Toroidal coupling of two counterpropaga...
