ITER离子回旋加速器加热和电流驱动系统（20 MW, 40-55 MHz）的持续设计由于其所受的广泛要求和接口限制而变得具有挑战性，其中一些是相互冲突的和/或仍处于高通量状态。这些要求包括在大范围的等离子体场景和磁场中运行（这促使使用宽带相控天线阵列），第一壁的高射频（RF）功率密度（以及相关的接近电压和电流限制的运行），对elm引起的负载变化的弹性，强烈的热负荷和机械负荷，长脉冲运行，高系统可用性，有效的核屏蔽，高密度的天线服务，远程处理能力。安装公差大，并具有核安全氚约束屏障功能。研发活动正在进行或准备验证关键天线组件（面向等离子体的法拉第屏、射频滑动触点、射频真空窗），以及射频电源、传输和匹配组件的合格性。为了验证和优化射频设计，对天线模型进行了大量的数值模拟和实验研究。本文重点介绍了各个系统组件的进展和突出问题。
The ongoing design of the ITER Ion Cyclotron Heating and Current Drive system (20 MW, 40–55 MHz) is rendered challenging by the wide spectrum of requirements and interface constraints to which it is subject, several of which are conflicting and/or still in a high state of flux. These requirements include operation over a broad range of plasma scenarios and magnetic fields (which prompts usage of wide-band phased antenna arrays), high radio-frequency (RF) power density at the first wall (and associated operation close to voltage and current limits), resilience to ELM-induced load variations, intense thermal and mechanical loads, long pulse operation, high system availability, efficient nuclear shielding, high density of antenna services, remote-handling ability, tight installation tolerances, and nuclear safety function as tritium confinement barrier. R&D activities are ongoing or in preparation to validate critical antenna components (plasma-facing Faraday screen, RF sliding contacts, RF vacuum windows), as well as to qualify the RF power sources and the transmission and matching components. Intensive numerical modeling and experimental studies on antenna mock-ups have been conducted to validate and optimize the RF design. The paper highlights progress and outstanding issues for the various system components.
