Analysis of the poloidal field magnet system leads in the IGNITEX experiment

Summary form only given. Extensive electromagnetic (EM) and magnetohydrodynamics analyses of the plasma discharge in IGNITEX have been carried out with the finite-element code PROTEUS. These results were used in the structural analysis code ABAQUS to investigate the thermomechanical stresses in the PF (poloidal field) leads. Various boundary conditions for the interface between the PF leads and the TF (toroidal field) magnet were considered. Part of the stresses in the leads relies upon the magnet. The time-dependent interaction between the EM and thermomechanical loads in the PF leads was analyzed. The stress distribution in the PF leads configuration and bearing loads was obtained
