Publication number: 20240090346Abstract: A monofilament (100) for producing an Nb3 Sn-containing superconductor wire (33) includes a powder core (1) with an Sn-containing powder, a reaction tube (3) composed of an Nb alloy that includes Nb and at least one further alloy component X. The powder core is disposed within the reaction tube. The monofilament also includes at least two sources (4) for at least one partner component Pk. A respective source includes one or more source structures at a unitary radial position in the monofilament. The source structures are at different radial positions. The alloy component X and the partner component Pk form precipitates XPk on reaction annealing of the monofilament in which Sn from the powder core and Nb from the reaction tube react to produce Nb3 Sn. The powder core is disposed in a moderation tube, which is disposed within the reaction tube. This provides a monofilament with improved current carrying capacity.Type: ApplicationFiled: August 18, 2023Publication date: March 14, 2024Inventors: Carl BUEHLER, Vital ABAECHERLI, Bernd SAILER, Klaus SCHLENGA, Manfred THOENER, Matheus WANIOR

Patent number: 11515462Abstract: For producing an Nb3Sn superconductor wire, restack rod process (RRP) subelements (1a; 60a) are grouped to form a bundle having an approximately circular cross section and are arranged together with filling elements (18a-18c) in an internally and externally round outer tube (19; 52). To the inside the filling elements form a serrated profile (25) for abutment against the hexagonal subelements, and to the outside they form a round profile (24) for direct or indirect abutment in the outer tube. In fabricating the RRP subelements, and before a reshaping with a reduction in cross section, an externally hexagonal and internally round casing structure (9) is provided, into which the remaining parts of the subelements are inserted, in particular, an annular arrangement of hexagonal Nb-containing rod elements (4), which are surrounded externally by an outer matrix (7, 61) and internally by an inner matrix (3).Type: GrantFiled: October 4, 2021Date of Patent: November 29, 2022Assignee: BRUKER EAS GMBHInventors: Matheus Wanior, Vital Abaecherli, Carl Buehler, Bernd Sailer, Klaus Schlenga, Manfred Thoener, Michael Field

Patent number: 10622537Abstract: A method for producing a semifinished product for a superconducting wire is provided herein. The semifinished product includes at least one NbTi-containing structure, such as a NbTi-containing rod structure. The NbTi-containing structure may be produced in layers by selective laser melting or selective electron beam melting of a powder that contains Nb and Ti. In the production of at least some layers of the NbTi-containing structure, during the production of an irradiated area provided for a material deposition of a respective layer, at least one process parameter of the selective laser melting or electron beam melting is varied in one or a plurality of first zones of the irradiated area as compared to one or a plurality of second zones of the irradiated area. The present techniques simplify introduction of artificial pinning centers into the NbTi-material of a superconducting wire or a semifinished product for such a superconducting wire.Type: GrantFiled: January 23, 2018Date of Patent: April 14, 2020Assignee: BRUKER EAS GMBHInventors: Vital Abaecherli, Klaus Schlenga, Bernd Sailer, Manfred Thoener, Matheus Wanior
