Three identical new WEST ion cyclotron resonance heating (ICRH) antennas have been designed, assembled then commissioned on plasma from 2013 to 2019. The WEST ICRH system is both load-resilient and compatible with long-pulse operations. The three antennas have been successfully operated together on plasma in 2019 and 2020, with up to 5.8 MW of coupled power. The load resilience capability has been demonstrated and the antenna feedback controls for phase and matching have been developed. The breakdown detection systems have been validated and successfully protected the antennas. The use of ICRH in combination with lower hybrid has triggered the first high confinement mode transitions identified on WEST.

三个相同的新型 WEST 离子回旋共振加热 (ICRH) 天线已被设计、组装，然后于 2013 年至 2019 年在等离子体上进行调试。 WEST ICRH 系统既具有负载弹性，又与长脉冲操作兼容。这三个天线已于 2019 年和 2020 年成功地在等离子体上一起运行，耦合功率高达 5.8 MW。负载弹性能力已经得到证明，并且相位和匹配的天线反馈控制已经被开发出来。故障检测系统已经过验证并成功保护了天线。ICRH 与低混合的结合使用触发了在 WEST 上确定的第一个高限制模式转换。
