Abstract
A multifilament superconductor having continuous, non-random pinning centers and including a plurality of parallel superconductive subfilaments of uniform cross-sectional area, the subfilaments being embedded in generally hexagonal pinning jackets, and the pinning jackets together forming a structure having a honeycomb-like cross-section, the jackets having a wall thickness that is substantially an integral multiple of the coherence length of the subfilaments in a predetermined field, the jackets together forming a plurality of continuous paths for fluxoids across the superconductor, whereby total pinning density of said superconductor is substantially increased, and the critical field strength of the superconductor is enhanced.
