Embodiment Construction

[0043] FIG. 1 shows the layers perpendicular to the longitudinal axis of the multi-filament conductor 1 according to the prior art in an oblique view from the front of the multi-filament conductor 1 . The multifilament conductor 1 has a strip-shaped substrate 2 with a front side 9 and a rear side 10 . The first direction 21 of the tape-shaped substrate 2 is defined as the longitudinal direction of the tape-shaped substrate 2 . Strip-shaped parallel strips of the buffer layer 4 are applied parallel to the first direction 21 on the front side 9 of the strip-shaped substrate 2 . The strips of cushioning layer 4 are spaced apart from each other and have a second direction 22 corresponding to the longitudinal direction of the strips of cushioning layer 4 . On the strips of the buffer layer 4 a superconducting layer 3 is formed, for example of YBCO material. A thin silver layer (Ag layer) 5 a and a copper layer (Cu layer) 5 b are formed on the superconducting layer 3 as a protecti...

Abstract

The invention relates to a multifilament conductor (1), designed with a ribbon-shaped substrate (2) and at least one superconductive layer (3), wherein the superconductive layer (3) is divided into filaments (20, 20'). The ribbon-shaped substrate (2) has a first direction parallel to the longitudinal extension thereof, and the at least one filament (20, 20') has a second direction parallel to the longitudinal direction thereof. The first and second directions form an angle not equal to zero. The multifilament conductor (1) can be designed in particular such that filaments (20, 20') are configured on the front (9) and back (10) of the conductor and are electrically connected to each other such that a transposed conductor is created. The invention further relates to a method for producing such a multifilament conductor (1).

Description

technical field [0001] The invention relates to a multifilament conductor with a tape-shaped substrate and at least one superconducting layer. At least one superconducting layer is formed on at least one surface of the tape-shaped substrate and divided into filaments. The tape-shaped substrate has a first direction extending parallel to its longitudinal direction, and at least one filament has a second direction extending parallel to its longitudinal direction. Furthermore, the invention relates to a method of manufacturing such a multi-filament conductor. Background technique [0002] Multifilamentary conductors with superconducting layers are used in particular as conductors in superconducting devices. Thus, multi-filament conductors can be used, for example, as superconducting windings in magnetic resonance tomographs, motors, generators or current limiters. In particular, when using high temperature superconducting (HTS) materials such as Y 2 BaCu 3 o 7 At the temp...
