Abstract
Covering the inside wall of the vacuum vessel with the ferritic boards (FBs) is planned in the third stage of the Advanced Material Tokamak Experiment (AMTEX) on JFT-2M. The total magnetic forces induced on FBs were calculated by the three-dimensional dynamic electromagnetic field analysis code, EMSolution, with solid magnetic elements to consider the coupled effects of eddy current and magnetization, and the skin effect of eddy current. The structural integrity was evaluated on the bolts fixing the FBs to the vacuum vessel.
