MeV/uの炭素イオンを患者に対し0-360度の如何なる方向からも高速3次元スキャニング法にて照射を行うことができる。また、二極・四極磁場が同時発生且つ、独立励磁可能な機能結合型超伝導電磁石を採用することで、全長14m、ビーム軌道半径5.5m、重量約300tと大幅な小型・軽量化を実現している。超伝導回転ガントリーは製造後、平成27年初頭より放医研への輸送並びに組立工事が行われ、同年9月に完成した。その後、ビームコミッショニングが行われ、所期の性能が得られていることを確認した。本発表では超伝導回転ガントリー研究開発の概要、並びにビームコミッショニング結果について紹介する。","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名,
