A program at Lawrence Livermore Laboratory to develop multifilamentary Nb/sub 3/Sn conductors suitable for use in constructing fusion research magnets has resulted in the commercial production of conductors having cross-sectional areas in the range 0.06 cm/sup 2/ to 0.84 cm/sup 2/. Critical current densities near the goal of 10/sup 4/ A/cm/sup 2/ at 12 T and 4.2 K have been obtained in conductors produced by two different techniques. The latest results of this program are presented and discussed.
