Research Abstract |
The interaction between Alfven Eigen-mode (AE) and fast-ions are experimentally investigated. The temporal evolutions of fast-ion energy spectra during the bursting activity of AE showed formation of clump and hole pairs in the energy spectra of fast-ions. It was found the energy of the clump decreases with the decrease of the mode frequency. The extension of simulation code MEGA to three dimensional magnetic field was completed with this project. A new simulation code AE3D, which calculates the eigen-function of AE, was also developed. Using these codes, a new interpretation for those experimental data was provided.
