Microfission chambers (MFCs) will measure the total neutron source strength in ITER. The MFCs will be installed behind blanket modules in the vacuum vessel (VV). Triaxial mineral insulated (MI) cables will carry signals from the MFCs. The joint connecting triaxial MI cables in the VV must be considered because the MFCs and the MI cables will be installed separately at different times. Vacuum tight triaxial connector of the MI cable has been designed and a prototype has been constructed. Performance tests indicate that the connector can be applied to the ITER environment. A small bending-radius test of the MI cable indicates no observed damage at a curvature radius of 100 mm.
微裂变室（MFC）将用于测量国际热核聚变实验堆（ITER）中的总中子源强度。微裂变室将安装在真空室（VV）包层模块的后面。三轴矿物绝缘（MI）电缆将传输来自微裂变室的信号。由于微裂变室和MI电缆将在不同时间分别安装，因此必须考虑在真空室中连接三轴MI电缆的接头。已设计出MI电缆的真空密封三轴连接器并制造了一个原型。性能测试表明，该连接器可应用于ITER环境。MI电缆的小弯曲半径测试表明，在曲率半径为100毫米时未观察到损坏。
