Pedestal stability comparison and ITER pedestal prediction
The pressure at the top of the edge transport barrier (or 'pedestal height') strongly impacts fusion performance, while large edge localized modes (ELMs), driven by the free energy in the pedestalExpand

Study of ion turbulent transport and profile formations using global gyrokinetic full-f Vlasov simulation
A global gyrokinetic toroidal full-f five-dimensional Vlasov simulation GT5D (Idomura et al 2008 Comput. Phys. Commun. 179 391)is extended including sources and collisions. Long time tokamakExpand

Conservative global gyrokinetic toroidal full-f five-dimensional Vlasov simulation
TLDR
A new conservative global gyrokinetic toroidal full-f five-dimensional Vlasov simulation (GT5D) is developed using a novel non-dissipative conservative finite difference scheme and enables robust and accurate simulations of tokamak micro-turbulence. Expand

Identification of a low plasma-rotation threshold for stabilization of the resistive-wall mode.
The plasma rotation necessary for stabilization of resistive-wall modes (RWMs) is investigated by controlling the toroidal plasma rotation with external momentum input by injection of tangentialExpand

Observation of an energetic-particle-driven instability in the wall-stabilized high-beta plasmas in the JT-60U tokamak.
We have observed a bursting mode in the high-beta plasmas above the ideal beta limit without a conducting wall. The mode frequency is chirping down as the mode amplitude increases, and its initialExpand

Dynamics and Stability of Resistive Wall Mode in the JT-60U High- β Plasmas
Abstract. The dynamics and stability of the resistive wall mode (RWM) are investigated in the JT-60U high-β plasmas, and the sustainment of highβ plasmas above the ideal no-wall βN-limit (βno-wall NExpand
