“干渉性の良い電界放出電子線”によって量子現象やミクロの世界の物体を新たに観察できるようになった。実例はアハラノフ・ボーム（AB）効果の実験をはじめとする量子現象や超伝導体中の磁束量子の動的観察である。この手法は，今後さらに干渉性の良い電子線の開発に伴って，先端技術から基礎物理に至る広範な分野において，有用なツールとなることが期待される。

New objects and quantum phenomena can be directly observed using the wave nature of field-emission electron beams. For example, the Aharonob-Bohm effect was confirmed to exist, which states that electrons can be physically influenced even when they never touch electromagnetic fields. Recently we observed the dynamics of magnetic vortices in superconductors. This technique will open a new window for directly observing the microscopic world in wide fields ranging from fundamental physics to advanced technologies together with the development of more coherent electron beams. In may talk, I will touch on 1-MV holography electron microscope we have just developed.
