摘要
为了实现EAST托卡马克1000s以上的稳态先进模式运行的最终物理目标,两电流带双环共振(RDL)离子回旋共振(ICRF)天线被选择用来加热,电流带是ICRF天线关键部件,它通过近场区的耦合把能量传输到等离子体中。本文通过有限元方法对电流带在等离子体破裂和等离子体垂直位移事件两种工况下进行了电磁计算,给出了电流带感应电流密度大小分布情况、磁感应强度大小分布情况以及电流带所受的电磁力。利用电流带所受的电磁力作为载荷对电流带进行了结构分析,分析结果为验证电流带结构的可行性提供理论依据,分析方法对未来更高功率的ICRF天线电流带进行电磁分析具有一定的借鉴价值。
In order to achieve the ultimate physical goal of the more than 1 000ssteadystate advanced mode on the Experimental Advanced Superconducting Tokamak （EAST）,a resonant double loop（RDL）of iron cyclotron range of frequency（ICRF） antenna,which consists of two current straps,was selected to heat.The current straps,which transmit energy power to plasma by coupling in the near-field region,are the key components of ICRF antenna.This paper covers the electromagnetic calculation for the current straps of ICRF antenna by the finite element method under the operating conditions of the disruption and the vertical displacement of plasma respectively.The results show the distributions of induced currents density and magnetic induction,as well as electromagnetic force on the current straps.Structural analysis was performed with the result of the electromagnetic force imposing on the current strap.The results provide theoretical basis for verifying the structure feasibility of current straps,and the analysis method has a certain reference value for future high-power ICRF antenna current straps relating with the electromagnetic analysis.
