Description
The poster presents a 0D methodology for the preliminary design of Toroidal Field (TF) coils, with a specific emphasis on Winding Pack (WP) sizing for compact, high-field tokamak devices (Bmax~20 T). In the early stages of design, when available data are limited, traditional 3D Finite Element (FE) models are often computationally prohibitive for rapid parametric optimization. To address this, a semi-analytical design approach using the MADMACS toolbox, developed by CEA-IRFM, is employed. This work provides an overview of recent updates to MADMACS, specifically the integration of High Temperature Superconductor (HTS) cable models. These materials are essential to withstand the extreme magnetic fields and operating currents; at these field levels, particular attention will be paid to structural aspects due to high Lorentz forces. Two HTS configurations (stacked and twisted tapes) are analyzed and compared across two different mechanical support strategies: wedging and bucking. Finally, this methodology is applied within the framework of the SupraFusion PEPR Program to the SF-Plant project, a conceptual high-field fusion device (with Pfus~2 GW and B0~10.6 T) aimed at assessing the feasibility of high-field reactors and proposing solutions to the major challenges of economically feasible fusion machines. The paper demonstrates the effectiveness of the proposed tool in dimensioning a viable TF winding pack for the SF-Plant in a bucking configuration.
