Abstract :
Some aspects of the operation of the poloidal-field (PF) system of the Fusion Ignition Experiment (IGNITEX) are analyzed. Stresses in the PF system due to the poloidal magnetic field are calculated for unsupported coils. When the structural eddy currents are taken into account, the stresses are considerably reduced. Stresses in the PF terminals due to the toroidal magnetic field are calculated for a terminal partially supported by the toroidal-field (TF) magnet. The maximum stresses occur in the lead located in the TF inner leg at the end of the flat top of the discharge. Stresses in the PF coils and the PF terminals are tolerable. A preliminary estimate of the perturbed vacuum magnetic field at breakdown is done, providing insight for the detailed design of the PF terminals
