Abstract :
The fabrication of bronze-processed multifilamentary Nb/sub 3/Sn wires having a critical current density of 840 A/mm/sup 2/ (4.2 K, 12 T) and an effective filament diameter of 6 mu m is reported. These values satisfy the specification required for the ITER Central Solenoid Scalable Model Coil. The measured time constant of the coupling loss in the wire is 4 ms at 12 T, in good agreement with the calculated result using B. Turck´s formula (1979).<>
