Effect of neoclassical toroidal viscosity on error-field penetration thresholds in tokamak plasmas.

A model for field-error penetration is developed that includes nonresonant as well as the usual resonant field-error effects. The nonresonant components cause a neoclassical toroidal viscous torque that keeps the plasma rotating at a rate comparable to the ion diamagnetic frequency. The new theory is used to examine resonant error-field penetration threshold scaling in Ohmic tokamak plasmas. Co...

Drift-magnetohydrodynamical model of error-field penetration in tokamak plasmas

A previously published magnetohydrodynamical MHD model of error-field penetration in tokamak plasmas is extended to take drift-MHD physics into account. In particular, diamagnetic and semicollisional effects are both fully incorporated into the analysis. The new model is used to examine the scaling of the penetration threshold in ohmic tokamak plasmas. © 2006 American Institute of Physics. DOI:...

Sawtooth pacing by real-time auxiliary power control in a tokamak plasma.

In the standard scenario of tokamak plasma operation, sawtooth crashes are the main perturbations that can trigger performance-degrading, and potentially disruption-generating, neoclassical tearing modes. This Letter demonstrates sawtooth pacing by real-time control of the auxiliary power. It is shown that the sawtooth crash takes place in a reproducible manner shortly after the removal of that...

Non-linear Mhd Studies in Toroidal Geometry - Disruptive Phenomena in Tokamak Plasmas*

NON-LINEAR MHD STUDIES IN TOROIDAL GEOMETRY DISRUPTIVE PHENOMENA IN TOKAMAK PLASMAS. Sawtooth oscillations and related fluid excitations are studied analytically and computationally, and some modifications relevant to high temperature regimes are presented. The role of the ideal kink in the sawtooth crash and a new theory of density limit disruptions are discussed. 1. NONLINEAR MHD STUDIES IN T...

Scaling of Ohmic Tokamak Error-field Penetration Thresholds in the Presence of Neoclassical Toroidal Viscosity

A model for field error penetration is developed that includes non-resonant as well as the usual resonant field error effects. The non-resonant components cause a neoclassical toroidal viscous torque that tries to keep the plasma rotating at a rate comparable to the ion diamagnetic frequency. The new theory is used to examine resonant error-field penetration threshold scaling in ohmic tokamak p...
