摘要
为实现EAST全托卡马克装置等离子体高参数,稳态运行目标,则需要高功率外部辅助加热,离子回旋共振(ICRF)加热是重要辅助加热手段之一。针对EAST装置运行要求和目标,设计了两套源功率为6MW,加热频率为30MHz~110MHz ICRF天线,用于等离子体加热。电流带是ICRF天线关键部件,它起到把射频波能量耦合到等离子体中重要作用。本文对EAST离子回旋共振(ICRF)天线电流带在真空环境条件下通过高频结构仿真(HFSS)开展了电性能分析计算,给出了S参数、电场分布情况、射频损耗分布情况。研究了ICRF天线耦合性能,评估了现有ICRF天线电特性,分析结果为后续电流带电热特性评估及结构优化提供了理论依据。
In order to achieve the goal of high parameter, steady-state running of EAST Tokamak, high power external auxiliary heating is needed, ion cyclotron range of frequency heating is one of the important auxiliary heating methods. According to the requirements and objectives of the operation of EAST device,source power for two sets of antenna is 6MW, and the heating frequency of ICRF antenna is30MHz~110MHz antenna, which is used for plasma heating. The current straps are key components of the ICRF antenna, which plays an important role in the coupling of RF wave energy to the plasma. In this paper, electrical performance analysis and calculation have been carried out on the EAST ion cyclotron resonance(ICRF) antenna current straps in vacuum environment by high frequency Structure Simulator(HFSS), and the S parameters, the electric field distribution and RF loss distribution are given. The coupling performance of the ICRF antenna is studied, and the electrical characteristics of the existing ICRF antenna are evaluated and the analysis results provide a theoretical basis for the evaluation and optimization of the electric heating characteristics.
