Superconducting flat tape cable magnet

摘要

A method for winding a coil magnet with the stacked tape cables, and a coil so wound. The winding process is controlled and various shape coils can be wound by twisting about the longitudinal axis of the cable and bending following the easy bend direction during winding, so that sharp local bending can be obtained by adjusting the twist pitch. Stack-tape cable is twisted while being wound, instead of being twisted in a straight configuration and then wound. In certain embodiments, the straight length should be half of the cable twist-pitch or a multiple of it.

主权项

1. A method of fabricating an electromagnetic coil using a superconductor cable comprising a plurality of flat, tape-shaped ribbon superconductor wires assembled to form a stack having a rectangular cross-section and a longitudinal axis, said method comprising:
providing a support surface about which said cable is to be wound, said support surface having at least one corner and at least one substantially straight portion; winding said cable about said support surface by bending said cable about said corner without twisting said cable, and twisting said cable in said substantially straight portion about said longitudinal axis.
