“…Some of the first generation of superconducting fusion devices launched in 1970s like the mirror fusion test facility (MFTF) [15] or Tore Supra [16] were still relying on NbTi superconductors while attempts were being made to utilize the potential of Nb 3 Sn higher performances. As examples, a Nb 3 Sn Insert Coil was integrated in MFTF [15] and tokamaks T-15 and TRIAM-1 constructed in the Kurchatov Institute and the University of Kyushu correspondingly utilized mainly Nb 3 Sn superconductors [17,18]. In addition, 5 large coils were constructed of Nb 3 Sn superconductor between 1979 and 2001 as technical demonstrators of material and design feasibility or as test facilities.…”

The overall 30 year Nb 3 Sn conductor program for ITER provides an unusual opportunity to look at the issues created by the application of novel Nb 3 Sn technology on a large scale. ITER design criteria have evolved to make use of the features of the industrialized material, exploiting advantages as well as managing the disadvantages. There are lessons from the successes and failures to be learned for the future application of very high current Nb 3 Sn strands in fusion and high energy physics. The behaviour of Nb 3 Sn strands in the large compound ITER conductors is still producing surprises after 25 years of development, industrial production and testing, with the Nb 3 Sn strain sensitivity and brittleness producing many more subtle design impacts than originally foreseen. The results now obtained at the end of the ITER production suggest that, as a novelty for Nb 3 Sn, there are options for conditioning the strands in the ITER conductors that can be applied during commissioning and which could reduce the impact of brittleness by as much as one third.

Three decades of conductor R&D, prototypes, model coils and actual fusion devices are reviewed with special attention to the drivers of the design. The conductor options are affected by the requirements typical of the fusion devices (large size and stored energy, high field, heat removal rate). The mechanical loads, operating voltage, ac loss and stability further restrict the freedom of the designer. On the other hand, the evolution of the available technologies for cryogenics and superconducting materials opens new frontiers for performance, reliability and cost. The lessons learned from the a dozen superconducting fusion devices are highlighted, starting from T-7, through MFTF, T-15, TRIAM, Tore Supra, LHD till the newest projects in construction, W-7X, EAST, SST-1, KSTAR. Some discussion is also devoted to the lessons that we keep refusing to learn.
