| Research Abstract |
The 3D effect by the externally imposed resonant magnetic perturbation field in LHD plasma has been studied. It has found that there is strong correlation between the dynamics of magnetic island structure and plasma flow. The behavior of the magnetic island in LHD can be divided by plasma beta and collisionality. These parameters, however, do not affect island dynamics directly, which implies the existence of the hidden parameter. The experimental fact has been found that the poloidal flow increases (decreases) prior to the magnetic island healing (growth).
