Outline of Final Research Achievements |
A possibility of the real-space in-plane structure analysis of layered systems was explored by using the neutron spin echo technique. Intensive development of the neutron polarizing supermirror, one of the most important neutron optical elements consisting of the neutron spin echo instrument, resulted in a marked extension in the bandwidth of the neutron-spin polarization, the momentum transfer range where the the reflected neutrons are polarized. This can offer a possibility to realize the main target of this study stated above and also give a big impact on the design of the polarized neutron instruments across the world because the capability of the instruments can be highly improved.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、中性子スピンエコー法を用いて実空間での空間密度関数の直接測定を目指し、同装置を構成する中性子スピン制御デバイスの一つである中性子偏極スーパーミラーの偏極可能波長領域の大幅な拡大を実現した。偏極中性子を用いた物質のミクロ構造やダイナミクスの解析は、基礎科学のみならず産業界でも広く利用されており、本研究により実現した偏極中性子利用の高度化は、J-PARC MLFだけでなく国内・海外を問わず他の中性子科学実験施設にインパクトを与え、学術及び産業界に広く貢献するものと考えられる。
