摘要：

利用全波方法对环形轴对称托卡马克等离子体中快波模式转换电子加热的机理进行了讨论，并针对EAST超导托卡马克上未来ICRF实验中可能的快波模式转换电子加热方案进行了模拟计算，为进一步ICRF实验方案设计优化提供了理论依据。

Abstract:

By using full wave method, the mechanism of electron heating through fast wave mode conversion in general toroidal axial-symmetric tokamak plasma is discussed, and then the scenarios in the future EAST ICRF experiments are simulated. The results are very beneficial for optimizing the EAST ICRH performances.

Key words: Fast wave, Mode conversion, Electron heating, EAST tokamak
