多くの宇宙機への搭載が予定されている. 既存の宇宙実績を維持するため大幅な設計変更を伴わずに, より大型の衛星に対応するためmu10は推力向上の必要性に迫られた. 光ファイバを用いた内部発光測定を行ったところ導波管内部に発光が確認され, マイクロ波の反射を引き起こしていることが判明した. 導波管におけるプラズマを抑制することを狙い推進剤の供給方法を変更したところ, ビーム電流の特性が変わった. グリッドの設計改良と合わせ, mu10は最終的に, 比推力は3160secを維持しながら, 推力は8.0mNから10.1mNへと増強に成功したのでここに報告する.", "subitem_description_type": "Abstract"}]}, "item_5_description_18": {"attribute_name": "内容記述",
