This paper evaluates the critical current of titanium-alloyed internal-tin, jelly-roll Nb{sub 3}Sn wire for use in the US-DPC coil. It was confirmed from 14 randomly-selected samples that the critical-current values were uniform and consistent: the non-copper critical-current density was approximately 700 A/mm{sup 2} at 10 T and 4.2 K in agreement with expectations. A 27-strand cable-in-conduit conductor (CICC) using the low-thermal-coefficient-of-expansion superalloy Incoloy 905 yielded a critical current 5--7% below the average value of the single-strand data.
