The effect of the feedback controller on superconducting tokamak AC lossesFunded under: FP5-EAECTP C
Superconducting coils in a tokamak are subject to AC losses when the field transverse to the coil current varies. A simple model to evaluate the AC losses has been derived and benchmarked against a complete model used in the ITER design procedure. The influence of the feedback control strategy on the AC losses is examined using this model. An improved controller is proposed, based on this study.
