Real-time estimation of radial location of magnetic islands in a tokamak from the associated temperature fluctuations

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...
