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 ...

Nb 3 Sn在聚变中的使用：从ITER生产中获得的经验教训，包括管理性能下降的选项

ITER的整个30年Nb 3 Sn导体计划提供了一个难得的机会，可以大规模研究新型Nb 3 Sn技术的应用所产生的问题。国际热核实验堆的设计标准已经发展到可以利用工业化材料的特性，既可以利用优点，也可以处理缺点。从大电流的Nb 3 Sn链在聚变和高能物理中的未来应用中可以吸取教训，从中汲取教训。经过25年的开发，工业生产和测试，Nb 3 Sn绞合线在大型复合ITER导体中的行为仍然令人惊讶，Nb 3 Sn应变敏感性和脆性产生的设计影响比最初预想的要细得多。现在，在ITER生产结束时获得的结果表明，
