| 摘要: |
| 中国聚变工程试验堆(CFETR)是一种新型的超导托卡马克装置, 极向场线圈(PF)在控制等离子体位行中起着关键作用。 CFETR PF线圈导体由Nb3Sn CICC 和NbTi CICC导体组成。为了确保PF线圈的稳定运行,本文采用1-D GANDALF对不同机械扰动和电磁扰动下PF导体的稳定性裕度,最小失超能量及温度裕度的进行了分析。分析结果表明 CFETR PF导体目前的设计能够充分满足安全裕度的要求。 |

| Abstract: |
| China Fusion Engineering Test Reactor (CFETR) is a new superconducting tokamak device. The Poloidal Field (PF) coil plays a key role in the plasma shape and location control. The updated design of CFETR requires both Nb3Sn as well as NbTi superconducting material in the shape of Cable-in-Conduit Conductor (CICC) to manufacture the PF coil. PF conductor design and stability analysis has been done using 1-D GANDALF in order to ensure the performance of PF coil. Stability margin,minimum quench energy and temperature margin are calculated under different mechanical disturbance electromagnetic disturbance. Analysis results reveal the present design adequately meets the stability margin criteria. |
