The theory of the kink mode during the vertical plasma disruption events in tokamaks

Journal Article Zakharov, Leonid E - Physics of Plasmas

This paper explains the existence of the m/n=1/1 kink mode during the vertical disruption event when the plasma has an electrical contact with the plasma facing conducting surfaces. It is shown that the kink perturbation can be in an equilibrium state even with a stable safety factor q>1, if the surface currents, excited by the kink mode, can flow through the conducting structure. The present theory suggests an explanation of the so-called sideway forces on the tokamak in-vessel components during the disruption event. For the general case of such wall touching kink modes, the energy principle is derived, which includesmore » the current sharing effect.« less

Ponderomotive feedback stabilization of external kinks and disruptions in tokamaks

Journal Article D`Ippolito, D A ; Myra, J R ; Jardin, S C ; ... - Physics of Plasmas

A novel mechanism for feedback stabilization of external kink modes and disruptions is proposed in which modulated radio-frequency (RF) antennas apply a stabilizing ponderomotive force (PF) to the plasma. The RF power required for {ital n}=1 kink stabilization in the Princeton Beta Experiment-Modified (PBX-M) [Phys. Fluids B {bold 2}, 1271 (1990)] is estimated, and it is shown that the idea can be tested with the existing antenna system. A simulation of a preliminary {ital n}=0 modulation experiment on PBX-M also shows that the PF can balance applied vertical field oscillations. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {italmore » Physics}.« less

The Theory of the Kink Mode during the Vertical Disruption Events in Tokamaks

Technical Report Zakharov, Leonid E

This paper explains the locked m/n = 1/1 kink mode during the vertical disruption event when the plasma has an electrical contact with the plasma facing conducting surfaces. It is shown that the kink perturbation can be in equilibrium state even with a stable safety factor q > 1, if the halo currents, excited by the kink mode, can flow through the conducting structure. This suggests a new explanation of the so-called sideway forces on the tokamak in-vessel components during the disruption event. __________________________________________________

Stabilization of the external kink and control of the resistive wall mode in tokamaks

Conference Garofalo, A M ; Turnbull, A D ; Strait, E J

One promising approach to maintaining stability of high beta tokamak plasmas is the use of a conducting wall near the plasma to stabilize low-n ideal MHD instabilities. However, with a resistive wall, either plasma rotation or active feedback control is required to stabilize the more slowly growing resistive wall modes (RWMs). Experiments in the DIII-D, PBHX-M, and HBT-EP tokamaks have demonstrated that plasmas with a nearby conducting wall can remain stable to the n = 1 ideal external kink above the beta limit predicted with the wall at infinity, with durations in DIII-D up to 30 times {tau}{sub w}, themore »« less

External kink modes as a model for MHD activity associated with ELMs

Technical Report Manickam, J

Tokamak plasmas in the high confinement mode of operation are known to exhibit edge localized activity referred to as ELMs. A model is proposed for the underlying cause in terms of the external kink mode. The build up of the current density near the plasma edge is shown to decrease the shear in the safety-factor, q, profile and lead to destabilization of the kink mode. The role of the plasma geometry and equilibrium profiles is discussed.
