中文摘要：

双涡流驱动快速充气阀已经在中国科学院等离子体物理研究所研制成功,为了快速、自动地给快速充气阀供气并精确测量充气量,本文设计搭建了一套快速充气阀自动补气及进气量精确测量系统,并用于EAST托克马克物理实验。在2015年EAST实验运行中,该系统满足了快速充气阀对自动补气系统的可靠性和准确性两方面的要求。该系统的成功研制为EAST定量研究快速充气对缓解等离子体破裂的效果提供给了重要的工具。

英文摘要：

Fast valve based on double-layer eddy-current repulsion for disruption mitigation wasdeveloped in the Institute of Plasma Physics of CAS. In order to meet the requirements of automatic gas supply and accurate measurement of gas amount, an automatic gas supply system wasdesigned and established. The whole system was successfully used in the EAST 2015 spring campaign for disruption mitigation study, which meets the accuracy and reliability requirement for automatic gas supply. This system can be used for quantitative research on themitigation effect of fast gas injectionon plasma disruption.
