国际热核聚变实验堆磁体线圈终端盒的设计

线圈终端盒（CTB）是国际热核聚变实验堆超导磁体系统的重要组成部分，其内部组件的漏热常常是整个磁体系统的主要漏热源之一，在很大程度上决定着低温系统的液氦消耗量。本文从降低热负荷的角度对CTB内部冷屏、超导电流传输线、电流引线、阀及冷却管路、外部盒体的设计进行了详细阐述，为最终结构的确定提供了理论依据。

Design of Coil Terminal Box for International Thermal-Nuclear Experimental Reactor Superconducting Magnet

Coil terminal box(CTB) is the important constituent of the International Thermal-Nuclear Experimental Reactor superconducting magnet system.The heat leak of its components is frequently the main heat load source of the(superconducting) magnet which decides consume of liquid helium of the cryogenic system.Designs of thermal shield,superconducting busbar,current leads,valves and cooling pipes,and outer box of CTB are detailed described from reducing heat load point of view.They provide the theoretical base for the final structure design.
