| Outline of Final Research Achievements |
Development of superconducting magnet using REBCO conductor has been carried out for future accelerators such as FCC in CERN, muon collider in USA, and SuperKEKB in Japan. Through this study, we have developed a HTS sextupole magnet using REBCO conductor and tested it at 77 K and 4.2 K. The magnet was excited up to the designed current without quenching and it was confirmed that the field quality was in an acceptable level for accelerator magnet. In addition to this, we have developed a critical current measurement method of REBCO conductors in high fields (B < 18 T) and at low temperature (4.2 K). And the critical currents of various commercial REBCO conductors were measured and compared as a first step of the high field magnet development.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により、REBCO線材の特性を十分に活かした加速器用特殊磁石の実現可能性を示すことが出来た。この実現は、衝突型加速器のルミノシテイー向上に大きく貢献し、高エネルギー物理学の進歩に大きな影響を与えるものと思われる。また、本研究で得られた低温(4.2 K)、高磁場(B <18 T)下でのREBCO線材の特性データは、加速器用高磁場磁石の開発のみでなく他分野の高磁場磁石開発にも有益な情報であり、今後の各種REBCO線材や磁石の開発を活発化するトリガーとなるものと思われる。
