中文摘要：

ITER ELM线圈设计用于控制等离子体边界局域模，线圈导体采用氧化镁矿物绝缘导体结构，其中铜导体采用内径33．3mm的中空铬锆铜导体。单匝ELM线圈最高运行电流为15kA，线圈运行过程中铜导体内通入去离子水冷却，设计冷却水流速为8m^3／s以保证线圈达到稳定运行温度。等离子体物理研究所完成了ITER内部线圈ELM原型线圈预研及制造并搭建了线圈流动阻力实验平台，并对ELM原型线圈进行压降测试实验。文中介绍了ITER装置中ELM线圈的压降测试平台的设计，对线圈压降实验数据进行分析。对比理论值与实验值，实验结果表明理论计算与实验值基本一致，实验结果具有可信性。

英文摘要：

ITER ELM coil was designed to control the edge local mode of plasma. The coil conductor was mineral insulated cables of MgO insulation, the copper conductor was a hollow CrZrCu conductor which the radius was 33.3mm. The highest run- ning current was 15kA. The deionized cooling water was put into the copper conductor. The flow velocity was designed as 8m^3/ s to ensure the coil can reach stable operating temperature. The Chinese Academy of Sciences （ASIPP） in Hefei completed the pre - researched and manufactured the ELM coils of ITER, coil flow resistance experiment platform was set up and the test for pressure drop was carried out. This article introduced the test platform of pressure drop for ELM coils in ITER and the data from the pressure drop test. The comparison between experiment data and theoretical computation showed that the theoretical values were consistent with the experimental data and the experimental results were credible.
