Electric joint design to be used in electromagnetic coils made with high-temperature superconducting tape, aspected wire, or cable

摘要

An electric joint design to be used in electromagnetic coils made with high-temperature superconducting tape, aspected wire, or cable. A terminal member contains an engraved twist-bend contour, which receives the coil and changes the direction of the coil by about 90 degrees without any hard-bends. A current lead is aligned with terminal section of the coil establishing an electric joint whose length is not limited by the coil geometry. Resistance is distributed along the length of the electric joint to reduce heat generation. The electric joint is placed away from the area where the magnetic forces are high to eliminate the problem of helium gas becoming trapped.
