The critical current of copper-stabilized multifilamentary Nb/sub 3/Sn wire was measured in magnetic fields up to 18 T at 4.2 K, 2.85 K and 2.18 K. The conductor investigated in the experiment was fabricated by a ''bronze'' process. Its external diam is 0.53 mm and it consists of 2886 filaments in a bronze matrix. The measurements show that the conductor has excellent superconducting properties. The extrapolated values of Bc/sub 2/, according to the scaling law for flux pinning, are 22 T and 23.8 T, at 4.2 K and 2.18 K, respectively. Transition temperature results are discussed. 14 refs.
