TF线圈结构是磁体系统中的主要结构部件，由TF线圈壳体、线圈间结构、重力支撑和界面结构组成。该结构封闭了 TF 线圈，以保护 CICC 免受机械、电气和热负载的影响，并支撑 7 对 PF 线圈。 10 多年来，我们一直在冷却和等离子操作期间对 TF 磁体的结构行为进行监测。通过审查TF磁体结构设计来研究高应力和大位移区域。将测量的结构行为与设计分析的估计行为进行比较。必须分析测量行为和估计行为之间的差异，并引入校正方法。该研究将有助于准确监测KSTAR超导磁体系统的安全运行以及开发用于DEMO的小型聚变反应堆。
The TF coil structures are the main structural components in the magnet system, and consist of TF coil cases, inter-coil structures, gravity support and interface structures. The structures enclose the TF coils to protect the CICC from mechanical, electrical and thermal loads, and support 7 pairs of PF coils. The structural behavior of TF magnet has been monitored during cool-down and plasma operation for over 10 years. High stress and large displacement regions are investigated through the review of the TF magnet structure design. The measured structural behaviors are compared with the estimated behavior from the design analyses. The discrepancy between measured and estimated behaviors has to be analyzed and a correction method will be introduced. The study will be helpful to monitor exactly the safety operation of the KSTAR superconducting magnet system as well as to develop a small fusion reactor for DEMO.
