Abstract
For producing an Nb3Sn superconductor wire, restack rod process (RRP) subelements () are grouped to form a bundle having an approximately circular cross section and are arranged together with filling elements (-) in an internally and externally round outer tube (). To the inside the filling elements form a serrated profile () for abutment against the hexagonal subelements, and to the outside they form a round profile () 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 () is provided, into which the remaining parts of the subelements are inserted, in particular, an annular arrangement of hexagonal Nb-containing rod elements (), which are surrounded externally by an outer matrix () and internally by an inner matrix ().
