| Outline of Final Research Achievements |
The first demonstration of X-ray microcalorimeter in space was finished without any trouble in the detecter,
resulting in handful but fruitful outcome around the cluster of galaxy. Although the mission did not last for long, the next challenge has started. I was responsible for the digital electronics of the calorimeter. Application of the next-generation calorimeter has been demonstrated under high background condition, which enhanced the technical readiness level of the detector. Black hole study using semi-analitical approach has suggested a magnetic field from a companion star might trigger the state transition of the accretion flow around the black hole.

| Academic Significance and Societal Importance of the Research Achievements |
短いながらも宇宙でX線精密分光を実現できたことにより、これまでの常識や観念の検証し覆すことができる可能性があることを提示することができた。また将来の精密分光に向けて、過酷なバックグラウンド環境であっても、超電導のデバイスが正常に動作し、サイエンスの抽出に決定的な役割を果たすことを示すことにも成功した。ブラックホールの電磁場放射や降着過程を理解するには磁場の役割が重要であることを示せたことで、今後の観測および理論的研究の役立つと考える。
