摘要：

为验证国际热核聚变实验堆计划（ITER）的气体注入系统(GIS)的设计是否能够满足装置运行的要求，以及为优化气体注入系统的气体加料控制模式提供直接而可靠的数据支撑。该研究在基于ITER GIS最终设计阶段提供的设计方案的基础上，在模拟实验平台上进行实验研究，该研究涉及燃料气体H₂、D₂以及杂质气体Ne、Ar、N₂及其混合气体的注入特性，包括其供气压力、注入管线结构对响应时间的影响。实验结论证明，气体注入系统的设计可以满足ITER装置的运行要求，且实验数据为ITER装置的气体控制模式，尤其是实现杂质气体快速、精确的控制，从而保障ITER装置安全运行，提供有力的技术支持。

Abstract: In order to verify the compatibility of the International Thermonuclear Experimental Reactor (ITER) Gas Injection System (GIS) design with operational requirements, and to provide accurate and reliable data for further optimization of its gas injection control mode. A simulation experimental platform based on the final design scheme of ITER GIS was conducted. This platform allows to study the injection characteristics of hydrogen (H₂), deuterium (D₂), neon (Ne), argon (Ar), nitrogen (N₂), and their mixtures, including the effects of supply pressure and injection pipeline structure on response time. Experimental conclusions have proven that the GIS design can meet the operational requirements of the ITER device, and the experimental data provides strong technical support for the gas control mode of ITER, especially for the rapid and precise control of impurity gases, thus ensuring the safe operation of the ITER device.
