Abstract :
The control of rotating magnetic instabilities in a tokamak can be achieved by localized injection of RF driven current. Real-time detection of the radial location of the unstable "magnetic islands" and of the RF power deposition has been achieved in a device designed, built and tested on the FTU tokamak
