Abstract

The addition of Ni to a superconducting strand can compensate its diamagnetic persistent-current magnetization over a portion of the beam-injection and acceleration stroke of the Superconducting Super Collider (SSC) magnet. The ferromagnetic addition may thus relieve the SSC magnet´s need for extremely fine filaments, the initial purpose of which was to minimize conductor magnetization. It is shown how the Ni could be incorporated into the strand itself, either in the form of replacement filaments or as a coating on the outside surface
