Experimental investigations of feedback circuits for suppressing resistive wall modes

Experimental investigations of feedback circuits for suppressing resistive wall modes

Feedback circuits have been designed and tested which reduce the component of a fluctuating magnetic field normal to a square coil. These circuits, when placed in an array covering a toroidal plasma, may be a practical alternative to a perfectly conducting shell for stabilizing resistive wall modes....
