a current lead for connecting a superconducting load system , in particular , a magnet coil , to a current feed point that is at a higher temperature than the load system comprises a flat , elongated carrier and a plurality of mechanical and electrical parallel high - temperature superconductors , wherein the htscs are disposed side by side on the carrier . the carrier is made of stainless steel , and a plurality of htscs are each disposed side by side on two opposite carrier sides of the carrier . the carrier is constituted in the shape of a plate with cut - outs . the current lead has a high current capacity and low thermal conductivity and provides improved emergency conduction properties in case of failure of the superconductivity in the htsc .
