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 …

Interaction between shear Alfvén wave (SAW) and energetic particles (EPs) is one of major
concerns in magnetically confined plasmas since it may lead to excitation of toroidal …

A second electron cyclotron emission imaging (ECEI) system has been installed on the
KSTAR tokamak, toroidally separated by 1/16th of the torus from the first ECEI system. For …

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 …

Modulation of turbulent electron temperature fluctuations () and density fluctuations () by an
m/n= 1/1 tearing mode island was observed in the core plasma region of the HL-2A …

The resonant interaction between energetic-particles and tearing mode is an unresolved
physics issue at present. It is found for the first time in tokamaks that an unstable tearing …

Strong resonant and non-resonant internal kink modes (abbreviated as RKs and NRKs,
respectively), which are also called resonant and non-resonant fishbones, are observed on …

Multi-scale interactions have been observed recently in the HL-2A core NBI plasmas,
including the synchronous coupling between $ m/n= 1/1$ kink mode and $ m/n= 2/1 …

A tokamak scenario with q (0) close to 1 has been achieved on HL-2A tokamak, which is an
internal transport barrier (ITB) at low central shear or a steady-state ITB combined with an H …

Millimeter-wave diagnostics have proven effective on various magnetic fusion devices
worldwide, yet the formidable challenges posed by the harsh environments of future burning …
