Quadratic programming optimization of the ITER PF coil scenario for reliable plasma breakdown integrated with IMAS

We present an ITER poloidal field (PF) coil scenario for reliable plasma breakdown using a two-dimensional ITER conductor model. Realistic engineering constraints, such as maximum voltage and current limits, are taken into account. To ensure reliable breakdown, magnetic constraints are imposed such that the toroidal electric field reaches ET = 0.3 V/m at breakdown while maintaining a high-quality field-null region with a poloidal stray field ∣B∣ < 3 mT. These constraints are implemented using a constrained quadratic programming method. The model provides an algorithm to determine PF coil power supply voltages that satisfy all constraints required for successful breakdown. The simulation code is developed using the ITER integrated modeling and analysis suite data structure to facilitate easy integration with future ITER integrated simulators.
