摘要

HIGH CURRENT CONDUCTORS AND HIGH FIELD MAGNETSUSING ANISOTROPIC SUPERCONDUCTORSABSTRACTImproved conductors and superconducting magnets aredescribed utilizing superconducting materials exhibitingcritical field anisotropy. This anisotropy is one inwhich the ability of the superconductor to stay in asuperconducting state depends on the orientation of amagnetic field applied to the superconductor with respectto the direction of current flow in the superconductor.This anisotropy is utilized in the design of conductorsand magnet windings comprising the superconductivematerial and specifically is directed to magnet windingsin which the direction of high critical current throughthe superconductor is parallel to the magnetic fieldproduced by current in these windings in order to obtainhigh critical fields. Particularly favorable examples ofa superconducting material are the so-called high Tcsuperconductors in which the primary supercurrent flow isconfined to 2 dimensional Cu-O planes. By arranging thesuperconductive windings so that the Cu-O planes aresubstantially parallel to the magnetic field produced bycurrent in these windings, the windings will be able towithstand high fields without being driven normal. Thismaximizes the magnetic field amplitudes that can beproduced by the magnet.
