After the first demonstration of successful operation with ion cyclotron resonance heating (ICRH) on TEXTOR using an antenna without Faraday shield (FS), a further comparison of an antenna with FS and an antenna without FS has been made over a wide range of plasma conditions (including the improved confinement regime on TEXTOR), in zero phase and pi phase operation, using various heating scenarios. No restriction in the operational conditions was found to exist for the screenless antenna. A theoretical analysis shows that antenna side limiters are sufficient to protect the antenna conductor from the plasma and that the plasma in front of the antenna can take over the role of the FS without introducing additional losses. The impact of the operation with both antennas on plasma temperature, density, energy, impurities, etc., is discussed in detail

イオンサイクロトロン共鳴加熱(ICRH)を用いたTEXTORにおけるファラデーシールド(FS)なしのアンテナによる成功した運転の最初の実証後、FS付きアンテナとFSなしアンテナのさらなる比較が、広範囲のプラズマ条件(TEXTORにおける改善閉じ込め領域を含む)にわたって、ゼロ位相およびπ位相運転において、様々な加熱シナリオを用いて行われた。スクリーンレスアンテナに対して運転条件に制限は存在しないことが見出された。理論解析により、アンテナ側面リミッターがプラズマからアンテナ導体を保護するのに十分であり、アンテナ前方のプラズマが追加の損失を導入することなくFSの役割を引き受けることができることが示される。両アンテナによる運転がプラズマ温度、密度、エネルギー、不純物などに及ぼす影響について詳細に議論する。
