摘要	为实现EAST装置等离子体高参数、稳态运行目标,需要高功率外部辅助加热,离子回旋共振（ICRF）加热是主要的辅助加热手段之一。由于ICRF天线运行频率高,因此ICRF天线的射频损耗较大,在天线表面的热负载较大。本文对EAST ICRF天线进行电磁分析的基础上得到天线的射频损耗分布。根据天线的射频损耗分布完成冷却流道设计,并通过对天线的热结构分析推算电流带的使用寿命,同时验证冷却流道结构设计的可行性与可靠性。
其他摘要	In order to achieve the goal of high parameter, steady-state operation of EAST （Experimental Advanced Superconducting Tokamak ）device, high power external auxiliary heating is necessary, and ion cyclotron range of frequency（ICRF）heating is one of the main auxiliary heating methods. Due to the high operating frequency of ICRF antenna, there will be large RF loss on ICRF antenna, corresponding to the heavy thermal load on the surface of antenna- In this paper, the electromagnetic analysis of ICRF antenna for EAST is performed, and the RF loss distribution of the antenna are obtained. Furthermore,the cooling channel is designed based on the RF loss distribution. Afterwards, the calculation of service lifetime ofstraps is based on the performed thermo-structural analysis,and the feasibility and reliability of cooling channel are also verified.
