Geodesic acoustic modes (GAMs) are ubiquitous oscillatory flow phenomena observed in
toroidal magnetic confinement fusion plasmas, such as tokamaks and stellarators. They are …

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 …

Since the last IAEA Fusion Energy Conference in 2018, significant progress of the
experimental program of HL-2A has been achieved on developing advanced plasma …

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 …

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 …

In this paper, we report the excitation of coherent density and potential fluctuations induced
by magnetohydrodynamic (MHD) activity in the edge plasma region of ADITYA-U tokamak …

The evolutions of MHD instability behaviors and enhancement of both electrostatic and
electromagnetic turbulence towards the plasma disruption have been clearly observed in …

The effect of magnetic islands on plasma flow and turbulence has been experimentally
investigated in the stellarator W7-X. Magnetic configurations with the 5/5 magnetic island …
