Abstract :
The temperature dependence of critical current in Nb/sub 3/Al/Cu multifilamentary strands fabricated by the Jelly-roll process has been measured to establish a data base for fusion magnet design. The measurements are performed in the temperature range of 4.2 to 16 K and in the magnetic field range of 0 to 16 T. From these data, we have produced empirical formulas available for conductor design work.
