摘要: 中国聚变工程实验堆(China Fusion Engineering Test Reactor,CFETR)中央螺线管(Central Solenoid)模型线圈超导磁体采用Nb3Sn和NbTi低温超导材料的CICC (Cable in Conduit Conductor)绕制而成,并用大量的超临界氦(SHe)冷却。通过低温氦循环泵能够有效的达到CICC磁体的超临界氦迫流冷却循环。为冷却CFETR CS模型线圈,需进行低温分配系统的建造。本文介绍CFETR CS模型线圈迫流冷却的流程设计。Abstract: Superconducting magnet of Central Solenoid (CS) model coil of China Fusion Engineering Test Reactor (CFETR) is made of Nb3Sn/ NbTi cable-in-conduit conductor (CICC), and operated by forced-flow cooling with a large amount of supercritical helium. The cryogenic circulation pump can be effectively to achieve the supercritical helium (SHe) circulation to the forced-flow cooled (FFC) cable-in-conduit conductor (CICC) magnet. A distribution system will be constructed for cooling the CFETR CS model coil. This paper presents the design of FFC process for the CFETR CS model coil
