Advanced Computational Model of ITER PF1 Coil for Manufacture Quality Control

An advanced computation model of the Poloidal Field coil #1 (PF1) of ITER tokamak is developed that involves a detailed description of the winding geometry. The model describes all basic current-carrying components, including turn joggles and inter-layer joggles of the coil. The model has been validated in comparative simulations with the simplified models and analytical calculations based on Ampere's law. A high computational accuracy of 7 · 10
^-7
is demonstrated. The error field produced by PF1 coil winding was estimated to be an order of magnitude below the threshold level. The model is planned to be applied for the quality control of the manufactured coil. The approach utilized in the PF1 coil model is quite generalized and flexible that makes it applicable for the modeling of other coils of the ITER magnet system.
