170GHz, 20MWのミリ波パワーをプラズマに入射するポロイダル可変・水平ポートランチャーの設計を進めている。伝送効率99%、ミラー上での熱負荷、プラズマ共鳴位置でのビームサイズなどの設計条件を満たす最適設計が得られた。その設計の妥当性評価を目的としたミリ波伝送モックアップを製作し、低電力実験を行っている。放射パターンの計測から、ミラーや導波管の最適設計が妥当であることを示す結果が得られた。そのミリ波設計とモックアップ試験の結果について報告する。

An ITER equatorial EC launcher has been designed to inject a 170 GHz, 20 MW millimeter wave beam to plasma with poloidal steering functionality in order to obtain more driven current at the peripheral region of plasma. The millimeter wave design to accomplish the high transmission efficiency more than 99% and to compliant with the requirement on heat load on the mirror s and beam size at the resonance location of plasma has been successfully developed. The mock-up to simulate the millimeter wave propagation in the launcher based on the design modification of the beam path is fabricated and the low power experiment is in progress. The field pattern measurement at the mock-up outlet indicates the validity of the design optimization of mirror's and the waveguide set-up. The design of the millimeter wave beam path for poloidal steering launcher and the experiments of the launcher mock-up are reported in detail at the workshop.
