摘　　要：射频波加热是磁约束核聚变装置的重要加热方式。本论文基于EAST装置离子回旋共振(ICRF)加热天线结构和运行参数,运用高频分析方法对ICRF天线开展电特性分析模拟,获得ICRF天线射频电势和电场分布特性,初步评估了天线电特性。基于天线电场分布特性和分析结果,从天线结构和运行相位两方面对ICRF天线电特性进行了优化,优化后通过分析结果表明:ICRF天线射频鞘电势和电场均有很大的改善和降低。分析方法和结果为EAST装置ICRF天线和其他同类装置设计、分析提供了有益的参考和借鉴。Radio frequency wave heating is an important heating method for magneticconfined nuclear fusion devices.Based on the structure of the ICRF antenna in EAST and operating parameters,this paper uses the high-frequency analysis method to simulate and analyze the RF potential and electric field distribution to evaluate the electrical characteristics of the ICRF antenna preliminarily.The electrical characteristics of ICRF antenna are optimized from the aspects of antenna structure and operating phase on account of the analysis.The analysis results showed that both the RF sheath potential and the electric field of the ICRF antenna were greatly improved and reduced after optimization.The analysis methods and results provide useful reference for the design and analysis of EAST ICRF antenna and other similar devices.
