ITER离子回旋频率范围（ICRH）加热系统需要在40-55 MHz的频率范围内耦合20 MW的功率，用于边缘局部模式的大范围场景。为了减轻相关风险，预计将在ITER上设计和安装两个端口插头天线，以便在长脉冲操作时提供总计20 MW的耦合功率[1]。在CYCLE联盟中，CEA对该天线设计的活动主要集中在法拉第屏设计（图1）和相关射频（RF）护套建模、用于天线附近边缘密度测量的反射计设计以及对天线远程处理/工具的贡献。本文对每个项目进行了概述，并提出了一些关键部件的研发活动。
The ITER ion-cyclotron range of frequency (ICRH) heating system is required to couple 20 MW of power in the frequency range 40–55 MHz for a large range of scenarios with Edge Localized Modes. To mitigate the associated risks, it is foreseen to design and install on ITER two port-plug antennas for a total of 20 MW coupled power on long pulse operation [1]. The CEA activity to this antenna design within the CYCLE consortium was focused on the Faraday screen design (Fig. 1) and associated radio frequency (RF) sheath modelling, the reflectometers design for edge density measurement in the antenna vicinity and a contribution to the remote handling/tooling of the antenna. This paper is an overview of each item and proposes some R&D activities on key components.
