Cost Analysis of High Temperature Superconducting Magnets for for Fusion and High Field Applications

Superconducting magnet strands costs can be evaluated for different strand geometries and material ratios through a production scaling factor P. P depends upon the cost of raw materials and purchase data. This cost analysis is critical for the exploration and development of High Temperature Superconducting (HTS) magnets for magnetic fusion, MRI & NRI magnets, and high field research magnets. The cost indices of interest are $kg−1 ,$m−1, and $ kA−1 m−1. The target specs for analysis are 4-20 K (LHe or Gas He etc.) / less of 77 K (LN2), high fields (TF / OH - 15-20+ T), and a high packing factor (Je > 80-100 A/mm2 (ITER TF coil Je is < 17 A/mm2).
