Outline of Final Research Achievements

Ultrafast observation technique with femtosecond and nanometer temporal- spatial resolutions would be very significant in material science and applications. We have designed and developed a first prototype of ultrafast electron microscopy (UEM) using a femtosecond-pulse and relativistic-energy electron beam. The femtosecond-pulse electron beam with the energy of 3 MeV and the pulse length of 100 fs have been generated using a radio-frequency electron gun. We succeeded to observe TEM images of gold and polystyrene nanoparticles in our UEM using the MeV-energy femtosecond electron pulses. In the ultrafast electron diffraction measurement, the single-shot observation is available. It would be very promising for studying the irreversible structural dynamics and making new discoveries in material science.
