AbstractThe largest pulsed superconducting coils ever built, the Central Solenoid (CS) Model Coil and Central Solenoid Insert Coil were successfully developed and tested by international collaboration under the R&D activity of the International Thermonuclear Experimental Reactor (ITER), demonstrating and validating the engineering design criteria of the ITER Central Solenoid coil. The typical achievement is to charge the coil up to the operation current of 46 kA, and the maximum magnetic field to 13 T with a swift rump rate of 0.6 T/s without quench. The typical stored energy of the coil reached during the tests was 640 MJ that is 21 times larger than any other superconducting pulsed coils ever built. The test have shown that the high current cable in conduit conductor technology is indeed applicable to the ITER coils and could accomplish all the requirements of current sharing temperature, AC losses, ramp rate limitation, quench behavior and 10 000-cycle operation.
摘要:全球最大的脉冲超导磁体——国际热核聚变实验堆(ITER)中心螺线管(CS)线圈,已成功完成研制并通过测试,验证了其工程设计方案的可行性。该线圈在测试中成功充电至运行电流46千安,产生13特斯拉的最大磁场,并以0.6特斯拉/秒的快速变化率运行,未发生失超。测试期间,线圈储存的能量达到640兆焦耳,是其他超导脉冲磁体的21倍。测试结果表明,管内电缆导体(CICC)技术确实适用于ITER线圈,能够满足电流共享温度、交流损耗、失超行为及10,000次循环运行等全部要求。
