| Outline of Final Research Achievements |
In general, superconducting detectors are fabricated by microfabrication system. I fabricated superconducting detector by machining system. I used superconducting materials such as niobium and niobium-titanium, which have high superconducting transition temperatures. I rolled and processed the plate by company, I succeeded to fabricate superconducting detector, that's the volume is 100 times as large as general one. I made a readout system using FPGA board to evaluate teh perfotmance of the detector. The detector was mounted on the refrigerator. The superconducting detector was worked.

| Academic Significance and Societal Importance of the Research Achievements |
分厚い超伝導体でとらえたエネルギーを従来の体積の小さな超伝導体に注入する構造を作る事で、エネルギー効率が高く感度の高い検出器が開発できるようになる。また、微細加工で取り付けができない超伝導材料を利用することが可能になる。
開発した超伝導検出器は、十分な厚みを持つ超伝導体を曲げることができる基材上に取り付けた構造を持つ。これにより曲がった面などへの取り付けが可能であり、従来では実現出来なかっ円筒の表面にびっちりと検出器を取り付け、感度のない部分を最小化する等のセットアップが可能となった。
