No-Insulation Multi-Width Winding for High Temperature Superconducting Magnets

An HTS magnet having a stack of a plurality of double-pancake (DP) coils is disclosed, with each DP coil having a first superconducting coil and a second superconducting coil. The plurality of DP coils have varying widths, with DP coils with the widest widths at the top and bottom of the stack, and DP coils with the narrowest coils located substantially at a midpoint of the stack. The DP coils omit turn-to-turn insulation, or have minimal turn-to-turn insulation.
