Outline of Final Research Achievements |
We have succeeded to develop a femtosecond time-resolved electron diffractometer using high-brightness 100-fs electron pulses at an energy of 3.1 MeV generated by a radio-frequency acceleration-based photoemission gun. Using the diffractometer, we obtained high-quality diffraction images from single gold crystals and Mica crystals with a single shot. The measurements were successful in facilitating the detection of higher-order diffraction patterns with a scattering vector up to 1.47/A and an excellent spatial resolution of 0.02/A. The demonstration indicates that our relativistic ultrafast electron diffractometer is applied to facilitate the study of ultrafast structural dynamics of reversible and irreversible processes in organic/inorganic molecules and protein materials at the femtosecond time-scale.
