| Outline of Final Research Achievements |
In order to observe motion of fine magnetic strictures such as magnetic skyrmions, a method of time-resolved observation by a pulsed electron beam with a photocathode type electron gun and a direct electron detector was developed in a low-voltage transmission electron microscope. We have succeeded in generating sub-micro second pulsed electron beams at high intensity. In addition, we have realized single-shot imaging at high signal-to-noise ratio using synchronous measurement. A time-resolved transmission electron microscopy with continuous image acquisition at 500 ns interval was established by using high-speed deflector.
