Multifilament Superconductor, as well as Method for its Production

摘要

A multifilament superconductor (1) has a core area (2) and several superconductor filaments (4). The superconductor filaments (4) each have a core (6) made of a powder metallurgically produced superconductor. The core area (2) is enclosed by an outer shell (3) made of a non-superconducting metal or a non-superconducting alloy (8, 10). The outer shell (3) has at least one reinforcement element (9) made of tantalum or a tantalum alloy.
