Abstract
A semifinished wire () for a superconducting wire containing Nb3Sn has a Cu stabilization cladding tube (), a ring-shaped closed diffusion barrier () in the inside of the Cu stabilization cladding tube () and a plurality of PIT elements () in the inside of the diffusion barrier (), each having a cladding () containing Cu, a small tube (), and a powder core () containing Sn. The small tube () consists of Nb or an alloy containing Nb and the diffusion barrier () has a percentage of area ADF in cross-section of the semifinished wire () of 3% ADF 9% and a wall thickness WDF with 8 μm≦WDF≦25 μm. A plurality of filler elements () are arranged inside the diffusion barrier (), with the inner sides of the filler elements () abutting the PIT elements ().
