Stabilization of Line Tied Resistive Wall Kink Modes with Rotating Walls
نویسنده
چکیده
A method suggested by Gimblett[(C. G. Gimblett, Plasma Phys. Controlled Fusion 31, 2183 (1989)] for stabilizing resistive wall modes by using a rotating double wall configuration is applied to a line tied screw pinch equilibrium. The line tied boundary conditions provide an additional stabilizing mechanism relative to instabilities present in periodic cylinders. For a given equilibrium, there exist an optimal spacing between a stationary and a rotating wall which minimizes the critical wall rotation frequency for stabilization.

Control of External Kink Modes Near the Ideal Wall Limit Using Kalman Filtering and Optimal Control Techniques
The first experimental demonstration of active feedback suppression of rotating external kink modes near the ideal wall limit in a tokamak using Kalman filtering to discriminate the n = 1 kink mode from background noise is presented [1]. The Kalman filter contains a model that captures the dynamics of a rotating, growing n = 1 kink mode. Suppression of the external kink mode is demonstrated usi...
متن کاملStabilization of the resistive wall mode by a rotating solid conductor.
Stabilization of the resistive wall mode (RWM) by high-speed differentially rotating conducting walls is demonstrated in the laboratory. To observe stabilization intrinsic azimuthal plasma rotation must be braked with error fields. Above a critical error field the RWM frequency discontinuously slows (locks) and fast growth subsequently occurs. Wall rotation is found to reduce the locked RWM sat...

The rotating wall machine, a basic plasma physics experimental facility, has been constructed to study the role of electromagnetic boundary conditions on current-driven ideal and resistive magnetohydrodynamic instabilities, including differentially rotating conducting walls. The device, a screw pinch magnetic geometry with line-tied ends, is described. The plasma is generated by an array of 19 ...
متن کاملObservation of resistive and ferritic wall modes in a line-tied pinch.
The resistive wall mode is experimentally identified and characterized in a line-tied, cylindrical screw pinch when the edge safety factor is less than a critical value. Different wall materials have been used to change the wall time and show that the growth rates for the RWM scale with wall time and safety factor as expected by theory. The addition of a ferritic wall material outside the condu...
متن کاملModeling of active control of external magnetohydrodynamic instabilities
A general circuit formulation of resistive wall mode ~RWM! feedback stabilization developed by Boozer @Phys. Plasmas 5, 3350 ~1998!# has been used as the basis for the VALEN computer code that calculates the performance of an active control system in arbitrary geometry. The code uses a finite element representation of a thin shell structure in an integral formulation to model arbitrary conducti...
