Neoclassical tearing modes

open access: yesPlasma Physics and Controlled Fusion, 2000
Neoclassical tearing modes are one of the most serious concerns for operation on a next-step tokamak device. The modes occur on present tokamaks at normalized pressure (beta (N)) values comparable to those envisaged For baseline scenarios in future devices, such as ITER-FEAT.

Current-interchange tearing modes: Conversion of interchange-type modes to tearing modes

Physics of Plasmas, 2010
It is shown that, in addition to usual neoclassical tearing modes, another type of nonclassical tearing mode exists in tokamaks: viz., current-interchange tearing modes (CITMs). CITMs are directly driven by unstable pressure-driven electromagnetic or electrostatic modes of the interchange type (e.g., interchange/ballooning modes, drift waves, etc.) due

Nonlinear Saturation of Tearing Mode Islands

Physical Review Letters, 2005
New, rigorous results for the tearing island saturation problem are presented. These results are valid for the realistic case where the magnetic island structure is non-symmetric about the reconnection surface and the electron temperature, on which the electrical resistivity depends, is evolved self-consistently with the island growth.

Saturation of the tearing mode

The Physics of Fluids, 1977
A quasi-linear analytical model is used to describe the nonlinear growth and saturation of tearing modes with mode number m⩾2. The saturation of the magnetic island growth is the quasi-linear development of a single mode rather than a mode coupling process.

Tearing modes at the magnetopause

Journal of Geophysical Research: Space Physics, 1981
This paper examines the possible occurrence of tearing modes in the dayside magnetopause. First, the expected magnetic signature of tearing, as obtained from existing theory, is reviewed. Magnetometer data from one terrestrial magnetopause crossing and one crossing of Jupiter's magnetopause are then examined in detail.

Interaction of tearing modes

The Physics of Fluids, 1979
A fully developed tearing mode modifies the magnetic field profile. The effect of this profile modification on the linear growth rate of a different tearing mode in a slab and cylindrical geometry is investigated.

The nonlinear tearing mode

1984
A series of nonlinear computations of tearing-mode development have been performed which achieve higher values of the magnetic Reynolds number and larger wavelengths than previously considered. A prime candidate for the realization of dynamic reconnection is the resistive magnetic tearing mode, a spontaneous instability of a stressed magnetic field ...
