Stabilization of global MHD instabilities by toroidal plasma rotation [PDF]

, 1995
Theoretical study and experimental observations suggest that rotation can play a crucial role in determining plasma stability. Since conventional magnetohydrodynamic (MHD) analysis ignores rotation, more advanced computational tools are being developed ...

Intrinsic toroidal plasma rotation in the scrape-off-layer [PDF]

The origin and nature of intrinsic toroidal plasma rotation in the scrape-off-layer are theoretically investigated. We discuss and analytically estimate three mechanisms that give rise to SOL toroidal rotation: turbulent momentum transport associated ...

New insights into error field assessment from mode coupling effects based on RMP spectrum scanning experiments in EAST

Nuclear Fusion
Numerical simulations concerning the spectrum of resonant magnetic perturbation (RMP) on field penetration threshold in EAST are presented, since the underlying physics is not well understood by the linear response model.

Effects of the applied magnetic field phasing on the neoclassical toroidal viscosity and toroidal rotation in JT-60SA

, 2017
Error field correction coils (EFCCs) will be installed in JT-60SA to apply the perturbed magnetic field for avoidance of the locked mode and control of the edge localized modes (ELMs).

Alpha particle-driven toroidal rotation in burning plasmas

, 2011
The mechanism of a torque intrinsically produced by alpha particles and the subsequent possibility to create significant toroidal rotation and shear are numerically investigated. In steady-state DEMO plasmas, regardless of the magnetic configuration, the

A novel high-performance confinement regime in a tokamak driven by tearing mode locking and rotation shear

Nuclear Fusion
In magnetically confined fusion plasmas, tearing mode (TM) locking is conventionally regarded as detrimental, often halting rotation and triggering disruptions.

Physics and modeling of toroidal rotation and torque sources in JT-60U

, 2016
The integrated modeling regarding transport phenomena has progressed significantly in recent years. Toroidal momentum transport and toroidal rotation physics remain less understood than physics of either heat or particles.
