Neoclassical, semi-collisional tearing mode theory in an axisymmetric torus

Time-dependent Simulations of Neoclassical Tearing Mode Stabilization in TCV

Multimachine Extrapolation of Neoclassical Tearing Mode Physics to ITER

New data and inter-machine comparisons are presented exploring the role of rotation, ρ and error fields in governing tearing mode β limits. It is found that conventional aspect ratio tokamak βN limits due to 2/1 tearing modes fall from values in excess of 3 with the usual strong neutral beam torque injection, to ~2 in low torque plasmas for ITER-like baseline scenarios. The fractional rates of ...

H-mode plasma transport simulation in ITER with effect of neoclassical tearing mode

Integrated simulations of saturated neoclassical tearing modes in DIII-D, Joint European Torus, and ITER plasmas

A revised version of the ISLAND module ͓C. tokamak discharges in order to investigate the adverse effects of multiple saturated magnetic islands driven by neoclassical tearing modes ͑NTMs͒. Simulations are carried out with a predictive model for the temperature and density pedestal at the edge of the high confinement mode ͑H-mode͒ plasma and with core transport described using the Multi-Mode model. ...

Plasma rotation effects on neoclassical tearing modes

The effect of an equilibrium sheared ow on the nonlinear evolution of a neoclassical tearing mode is investigated by estimating the inuence it has on the inner and outer layer dynamics of the mode. Two complementary approaches are adopted. A generalized Rutherford model calculation is carried out to estimate the ow contributions to the polarization current term in the inner layer. For the ou...
