Outline of Research at the Start

核融合炉の巨大で複雑な超伝導マグネットの製作課題を解決する先進設計案として、組立・分解を可能とする分割型高温超伝導マグネットを提案している。本研究では、1) 強磁場・照射環境を踏まえた接合特性詳細分析、2) 強磁場用超伝導センサー製作とクエンチ検出特性影響因子の解明、3) 放射化計算に基づく分割型高温超伝導マグネット保全シナリオ検討、を通して、強磁場・照射特性を踏まえた分割型高温超伝導マグネットの建設・運用・保全シナリオの構築を行う。

Outline of Final Research Achievements

For consideration of construction, operation and maintenance of segmented high-temperature superconducting (HTS) fusion magnets, we carried out 1) Detailed evaluation of REBCO tape and joint characteristics under high magnetic field and irradiation environment, 2) Fabrication of superconducting quench detectors for high field and clarification of factors affecting quench detection, and 3) Consideration of design and maintenance of the segmented HTS magnets taking into account high field and irradiation environments. In 1), we obtained temperature and magnetic field dependence of the interface resistance inside the REBCO tape, and the critical current characteristics of the REBCO tape with proton irradiation at liquid nitrogen temperature. In 2), we demonstrated the quench detection of various REBCO coils using the Nb-Ti quench detector and developed the Nb3Al quench detector. In 3), we evaluated the effects of magnetic field and irradiation on magnet design.

Academic Significance and Societal Importance of the Research Achievements

将来の核融合炉のためには,強磁場・照射環境を踏まえた分割型高温超伝導マグネットの建設・保守・運用を考える必要があり,本成果はそれに資するものである.また本研究は世界で初めてREBCO線材内部の層間抵抗の温度磁場依存性を非破壊評価し,そこから抵抗発生メカニズム解明に向けた仮説を立てるに至った.本研究で行ったREBCO線材の照射特性は核融合マグネットの課題抽出をするために重要な知見である.さらに磁場環境下でのREBCOコイルの早期クエンチ検出の原理実証と強磁場用超伝導クエンチセンサ開発により,強磁場環境における早期クエンチ検出技術確立への課題抽出を行うこともできた.
