The reversed magnetic shear (RMS) configuration is believed to be one of the most
promising advanced scenarios to achieve steady-state operation in the future large-scale …

Currents driven by radio frequency (rf) waves in the interior of magnetic islands can stabilize
deleterious tearing modes in tokamaks. Present analyses of stabilization assume that the …

Tearing modes are MagnetoHydroDynamics (MHD) instabilities that reduce the performance
of fusion devices. They can however be controlled and suppressed using electron cyclotron …

The influence of driven current on the m/n= 2/1 resistive tearing mode is studied
systematically using a three-dimensional toroidal magnetohydrodynamic code. A uniform …

The RF stabilization of tearing modes with current condensation has the potential to
increase stabilization efficiency and loosen power localization requirements. Such benefits …

A spontaneous heating process is found to arise in a system where a magnetic island is
present due to a linearly unstable tearing mode. The parity, the relative phases and the …

The nonlinear RF current condensation effect suggests that magnetic islands might be well
controlled with broader deposition profiles than previously thought possible. To assess this …

Sharp temperature gradients in a magnetically confined plasma can lead to turbulent motion
of the plasma. This turbulence in turn enhances the transport of heat across magnetic field …

Numerical modelling on tearing mode stabilization by RF current due to electron cyclotron
current drive (ECCD) has been carried out for the purposes of disruption avoidance …

The effect of electron cyclotron current drive (ECCD) on the multi-helicity neo-classical
tearing modes (2/1 and 3/2 NTMs) in tokamak plasmas is numerically studied by adopting a …
