| Research Abstract |
The first prototype of femtosecond time-resolved relativistic transmission electron microscopy has been developed using photocathode radiofrequency (RF) gun in world for the direct visualization of ultrafast structural dynamics in matter. A 100 fs MeV electron beam with emittance of 0.2 mm-mrad was generated in RF gun. The observations of both electron diffraction and microscopy imaging were succeeded in the prototype.
