これによって0-360度の任意の方向から重粒子線が照射できるようになり、高精度な治療が可能となる。 重粒子線回転ガントリーは、小型化のため、10台の機能結合型の超伝導電磁石により構成されている。 超伝導電磁石は2極と4極が独立励磁できるようになっており、高い磁場均一度が求められる。 また、エネルギーを430 MeV/uから56 MeV/uまで変化させ深部線量分布を調整するが、 治療のために430-56 MeV/uの間を202ステップ、一ステップあたり100 ms程度で下げる必要がある。 そのため我々は全電磁石の磁場測定を行い、そのうち一台で高速励磁試験や磁場整定時間の測定を行った。 本会議ではこれらの結果について報告する。","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期,
