Abstract

A multifilament superconductor (1) has a core area (2), several superconductor filaments (7) and reinforcement filaments (6). The superconductor filaments (7) and the reinforcement filaments (6) are arranged, so that they have a regular two-dimensional matrix (5) in the cross-section of core area (2). The reinforcement filaments (6) consist of tantalum or a tantalum alloy, and the superconductor filaments (7) each have a core (8), made from a powder metallurgically produced superconductor, which is enclosed by an inner shell (9), made of a non-superconducting metal or a non-superconducting alloy. The core area (2) is enclosed by an outer shell (3), made of a non-superconducting metal or a non-superconducting alloy.
