摘要： A process for joining ceramic superconductor fibers with a channel to fabricate a superconductor wire includes concertedly drawing the fibers and the channel together to feed the fibers into the channel. A flowable solder paste is continuously dispensed into the channel over the fibers. The combination of channel, fibers and solder paste is then subjected to a rapid rise in temperature which melts the solder. The molten solder is then frozen to encase the fibers in the solder and attach the solder to the channel to create a superconductor wire.

摘要： A system and method for supporting a superconductor tape during a heat treating process includes a cylindrical spool which is longitudinally split into a first half and a second half. Clamps are provided to hold the halves of the spool together in a first configuration. Additionally, shims are provided which can be positioned between the halves and which, in cooperation with the clamps, hold the halves of the spool in a second configuration. Before the heating process, the superconductor tape is wound onto the spool while it is being held by the clamps in its first configuration. The clamps are then released and the superconductor tape is subjected to the heating process. After the heating process, the shims are positioned between the halves, and the clamps are reengaged to form the spool in its second configuration. The superconductor tape can then be removed from the spool.

摘要： A multifilamentary superconducting cable has two parallel spaced-apart guide wires. A first layer of mutually parallel superconducting filaments is woven partially around and between the guide wires in a transposed braid. Likewise, a second layer of mutually parallel superconducting filaments is woven partially around and between the guide wires in a transposed braid. Thus, the two layers overlap each other as the respective layers pass between the guide wires. The two superconducting layers and two guide wires are enclosed in a helical copper duct, with the guide wires being oriented within the duct.
