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.

3基の同一の新型WESTイオンサイクロトロン共鳴加熱(ICRH)アンテナが設計され、2013年から2019年にかけて組み立てられ、プラズマ上で試運転が行われた。WEST ICRHシステムは、負荷耐性に優れ、長時間パルス運転に対応可能である。3基のアンテナは、2019年と2020年にプラズマ上で同時運転に成功し、最大5.8 MWの結合電力を達成した。負荷耐性能力が実証され、位相および整合のためのアンテナフィードバック制御が開発された。絶縁破壊検出システムが検証され、アンテナの保護に成功した。ICRHを低域混成波加熱と組み合わせて使用することにより、WESTで初めて確認された高閉じ込めモード遷移が誘発された。
