Abstract
We calculate a set of ITER poloidal field (PF) coil currents at the initial magnetization phase using the quadratic programming algorithm. The optimization is performed by exploiting the total magnetic energy of the ITER PF system as a cost function to be minimized. We also develop a simple analytic model which can make a rapid evaluation of temperature margin of superconducting PF coils for a given set of coil currents. This calculation is necessary for a quick examination of the compatibility of the PF scenario with engineering constraints. For an easy adaptation to the future integrated ITER simulator, all modules are developed using the ITER Integrated Modeling Analysis Suite (IMAS) data structure and the Kepler framework.
