000119499 520__ $$aThis paper describes recent progress in the development of Nb3Sn wires in Switzerland using the internal tin method The work war carried out in close collaboration between the Fusion Technology Division of CRPP and Swissmetal, with the emphasis on conductors suitable for fusion magnets. The manufacturing process is hared on tbe tubular extrusion of a niobium-copper composite, followed by the cold working of the composite containing a tin core. 19 Nb-Cu-Sn subelements were assembled inside a tantalum diffusion barrier and a copper can and subsequently reduced to wire size by swaging and drawing. The intention was to obtain non-reacted filament sizes of typically 3 mu m in 0.8 - 1 mm wires. The evolution of the design 3 mu m manufacturing process are discussed. Experience gained with model conductors bar been used to guide the design. The strands have been evaluated with respect to electrical and mechanical properties. In particular, critical current densities in the non-copper area exceeding 750 A/mm(2) at 12 T and 4.2 K have been achieved.
