The experimental research over last two years on the J-TEXT tokamak is summarized and
presented in the paper. The high-performance polarimeter-interferometer developed on J …

Since the first plasma realized in 2020, a series of key systems on HL-3 (known as HL-2M
before) tokamak have been equipped/upgraded, including in-vessel components (the first …

The first comprehensive measurements of plasma flows and fluctuations nearby static
magnetic islands driven by resonant magnetic perturbations are presented. These …

The turbulence and flows at the plasma edge during the L–I–H, L–I–L and single-step L–H
transitions have been measured directly using two reciprocating Langmuir probe systems at …

The links between the microscopic dynamics and macroscopic threshold physics of the L→
H transition are elucidated. Emphasis is placed on understanding the physics of power …

Turbulence spreading and its effects on the edge flows and turbulence during sawtooth
cycles in the J-TEXT tokamak plasmas are presented. These experiments were performed …

The Langmuir probe observed an increase in density and floating potential fluctuations after
the sawtooth crash at the edge of HL-2A neutral beam injection heated plasma. This process …

This study numerically investigates the impact of the tokamak plasma shape (elongation,
triangularity, and aspect ratio) on the amplitude and period of sawtooth oscillations using the …

Enhancements of edge zonal flows, radial electric fields, and turbulence are observed in
electron cyclotron resonance heating-heated plasmas (Zhao et al 2013 Nucl. Fusion 53 …

Real-time prediction of the growth rate of internal kink modes and the timely implementation
of control measures are crucial for the stable operation of tokamak devices. In this study …
