Experiments and numerical analysis of eddy currents in the first wall of a fusion reactor

In order to simulate eddy currents induced in the first wall of a fusion reactor during plasma disruption, the authors have carried out a scale model experiment of a tokamak first wall with several ports and a numerical analysis based on the T-method developed by the authors in recent years. To measure the eddy current, a new type of probe is developed and named a split ring type of probe. Numerical results almost agree with the experimental ones, which assures the capability of the code and the measurement method
