Development of High Temperature Superconductor Coated Metal Fiber and Multifilamentary Wire

Lawrence D. Woolf; Fred Elsner; William A. Raggio; S. S. Pak; Terry L. Figueroa; J. D. Rose; R. Stephens; R.A. Olstad; Tihiro Ohkawa

Long superconductor fibers have been continuously produced by electrophoretically depositing REBa2Cu3O7−x powder onto a metal substrate fiber and sintering, then eletrophoreticaly depositing silver and sintering. After collecting the coated fiber on a take-up spool, the entire spool is batch-oxygenated to form the 90 K superconducting phase. Multiple fibers are then continuously unspooled and soldered into a copper channel to form the final multifilamentary high temperature superconductor wire. Superconducting fibers over 1000 meters long and multifilamentary wire 450 meters long have been produced.
