Effects of neoclassical toroidal viscosity on toroidal rotation under electron cyclotron resonance heating on J-TEXT tokamak

Nuclear Fusion
Influence of neoclassical toroidal viscosity (NTV) torque on intrinsic toroidal rotation caused by internal kink mode (IKM) in the J-TEXT tokamak is studied.

Drift-Alfvén wave turbulence induced particle and heat transport in I-mode pedestal plasmas

Nuclear Fusion
In this work, most of the weakly coherent mode (WCM) characteristics and the level of transport coefficients observed in I-mode pedestal plasmas of C-Mod are reproduced theoretically.

Impurity transport driven by kinetic ballooning mode in the strong gradient pedestal of tokamak plasmas

Nuclear Fusion
The impurity transport driven by kinetic ballooning mode (KBM) is theoretically studied in the DIII-D H-mode strong gradient pedestal plasmas. From the electromagnetic gyrokinetic equation, including the correction of the strong radial electric field ...

Tokamak plasma disruption precursor onset time study based on semi-supervised anomaly detection

Nuclear Engineering and Technology
Plasma disruption in tokamak experiments is a challenging issue that causes damage to the device. Reliable prediction methods are needed, but the lack of full understanding of plasma disruption limits the effectiveness of physics-driven methods.

Thermal transport induced by stochastic magnetic fields and turbulence during the thermal quench in tokamak plasmas

Nuclear Fusion
The timescale of thermal quench (TQ) remains a long-lasting issue in tokamak plasmas, which has not been fully understood yet. In this work, based on our previous thermal diffusion model and further considering the scattering caused by the electrostatic ...

The continuous evolution of the cold structure from localized origin to global collapse during the thermal quench on the J-TEXT tokamak

Nuclear Fusion
Understanding the origin of the tokamak thermal quench (TQ) remains a critical unresolved issue, particularly the causal link between initial localized temperature collapse and the final core energy collapse.

Physically constrained data-driven inversion of 2D fast-ion velocity distributions from single view CTS spectra

Nuclear Fusion
Reconstructing fast-ion velocity distributions from collective Thomson scattering (CTS) spectra is an ill-posed inverse problem due to the spectral nonlinearity, strong parameter coupling and measurement noise.
