The revealing and understanding of ultrafast structural-change induced dynamics are essential not only in physics, chemistry and biology, but also are indispensable for the development of new materials, new devices and applications. A new radio-frequency electron gun based ultrafast relativistic electron microscopy (UEM) has being developed in Osaka University to probe directly structural changes at the atomic scale with sub-100 fs temporal resolution in materials. The first prototype of femtosecond time-resolved relativistic-energy UEM has been constructed at end of October in 2012. Both relativistic-energy electron diffraction and image measurements have been succeeded using a femtosecond electron beam. In this paper, the development of the UEM prototype and the first experiments of relativistic-energy electron imaging were reported.
