Abstract: This disclosure teaches methods for making high-temperature superconducting striated tape combinations and the product high-temperature superconducting striated tape combinations. This disclosure describes an efficient and scalable method for aligning and bonding two superimposed high-temperature superconducting (HTS) filamentary tapes to form a single integrated tape structure. This invention aligns a bottom and top HTS tape with a thin intervening insulator layer with microscopic precision, and electrically connects the two sets of tape filaments with each other. The insulating layer also reinforces adhesion of the top and bottom tapes, mitigating mechanical stress at the electrical connections. The ability of this method to precisely align separate tapes to form a single tape structure makes it compatible with a reel-to-reel production process.
