講演題目：Nonlinear Dynamics of Turbulent Driven Magnetic Islands
Abstract：
Micro-scale turbulent fluctuations, zonal flows and MHD activity coexist in a plasma [1]. The study of
the interaction between turbulence and magnetic island is becoming an active field of investigation in
the plasma community [2,3,4,5]. However, there is still no clear experimental proof that both interact
significantly together and that turbulence can be at the origin of a strong MHD activity. Recently [6], by
means of numerical investigations it has been proposed a specific signature of turbulence driven
magnetic islands which could be used to demonstrate experimentally that islands can be triggered by
turbulence. Moreover, it has been shown that edge/interchange turbulence could also trigger, remotely,
(2/1) magnetic islands located in an inner region. It is also found that the island size could be larger than
the NTM onset threshold in ITER context [10]. Such turbulent driven seed island can be amplified by
the bootstrap current and lead to the self-consistent generation of an NTM by turbulence [7]. These
results will be reviewed in the context of tokamak physics.
