The sawtooth instability in tokamak plasmas results in a periodic reorganization of the core
plasma. A typical sawtooth cycle consists of a quiescent period, during which the plasma …

A review of the application of dimensionless parameter scaling techniques to magnetic
fusion experiments is presented. Because the methods of this type of analysis are not …

Progress in the area of MHD stability and disruptions, since the publication of the 1999 ITER
Physics Basis document (1999 Nucl. Fusion 39 2137–2664), is reviewed. Recent theoretical …

Utilizing a capability to vary neutral beam torque injection in the DIII-D [JL Luxon, Nucl.
Fusion 42, 614 (2002)] tokamak, m∕ n= 2∕ 1 neoclassical tearing mode onset thresholds …

The linear and nonlinear benchmarks between the CLT code and the M3D-C1 code for the
2/1 resistive tearing mode and the 1/1 resistive kink mode are presented. CLT is an explicit …

Experimental observations from a range of tokamaks show that neoclassical tearing modes
(NTMs) are triggered at lower plasma pressure when the sawtooth period is longer. A multi …

Abstract Washboard (WB) modes (Smeulders P et al 1999 Plasma Phys. Control. Fusion 41
1303) are a very common edge instability regularly observed in the H-mode regime in JET …

The reversed magnetic shear (RMS) configuration is believed to be one of the most
promising advanced scenarios to achieve steady-state operation in the future large-scale …

The likelihood of realising tokamak power-plants will be greatly improved by the discovery of
high-gain equilibria that resist the formation of small islands and hence avoid the disruptive …

The nonlinear growth of the internal kink mode is studied numerically using reduced
magnetohydrodynamic equations in cylinder geometry. For low Lundquist numbers, S< 10 7 …
