摘要
Oxford Instruments, Superconducting Technology (OI-ST) produces Nb3Sn wires by two major process routes: bronze and internal Sn, including modified jelly roll (MJR), Each process has its own strengths for particular applications. We report on MJR wire designed for prototype high energy physics accelerator magnet studies which achieved short sample non-Cu critical current density at 12 T, 4.2 K exceeding 2000 A/mm(2). We also report recent results from wires fabricated by other internal Sn methods, the bronze process, and powder-in-tube processes.
