This paper presents a pedagogical review of the physics of mesoscopic transport events and
their role in the breakdown of Fick's Law for turbulent transport in magnetically confined …

Interaction between a magnetic island and turbulence has been intensively studied in recent
years with advance of plasma diagnostics in various plasma experiment devices such as …

A decade-long operation of the Korean Superconducting Tokamak Advanced Research
(KSTAR) has contributed significantly to the operation of superconducting tokamak devices …

This paper presents a review of multi-scale interactions between small-scale turbulence and
large scale magnetic islands. In finite beta plasmas, zonal flows are relatively weak, and …

Magnetic islands (MIs), resulting from a magnetic field reconnection, are ubiquitous
structures in magnetized plasmas. In tokamak plasmas, recent researches suggested that …

The effect of island width on the multi-scale interactions between magnetic island (MI) and
ion temperature gradient (ITG) turbulence has been investigated based on the global …

We derive the E× B shearing rate associated with vortex flow inside a macroscopic magnetic
island (MI) in axisymmetric toroidal geometry. Due to the elongation of the MI and …

We present a gyrokinetic analysis of the vortex flow evolution in a magnetic island in
collisionless tokamak plasmas. In a short term ω¯ D t< 1, where ω¯ D is the secular …

The radial profiles of perpendicular flows in the presence of the $ m/n= 2/1$ magnetic island
were firstly measured in the HL-2A tokamak by hopping the work frequency of the Doppler …

We perform gyrokinetic simulations to study the effects of a stationary magnetic island on
neoclassical flow and micro-instability in a realistic KSTAR plasma condition. Through the …
