ITER-TF线圈需要产生12.5T的电流，大小为12m/spl×18m，对于这样的高场强线圈，采用反应-缠绕技术考虑了Nb/sub3/Al导体的适用性，实现了高可靠性和低成本的线圈制造。用该方法制作的Nb/Sub3/Al导体的最大弯曲应变为0.39%。由该菌株引起的i/subc/降解率预计将低于5%。对于60kA的工作电流，极限电流估计为65kA。使用Nb/Sub3/Al导体的TF线圈的交流损耗与使用Nb/Sub3/Sn导体时的交流损耗几乎相同。
The ITER-TF coil requires a generation of 12.5 T in a size of 12 m/spl times/18 m. For such a high field-large coil, the applicability of Nb/sub 3/Al conductors was considered with a react-and-wind technique which realizes high reliability and low cost for the coil fabrication. The maximum bending strain on the Nb/sub 3/Al conductor in use of this technique is 0.39%. I/sub c/ degradation due to the strain is expected to be below 5%. The limiting current is estimated as 65 kA for 60 kA operation current. AC loss in the TF coil with Nb/sub 3/Al conductor is almost the same as with Nb/sub 3/Sn conductor.
