One of the most fundamental problems of modern natural science is the direct observation of atomic motions in the course of various processes. For this purpose, in the experiment it is necessary to provide high spatial-temporal resolution. The solution to this problem is achieved by using a pulsed electron beam of ultrashort duration to create a stroboscopic diffraction pattern in the method of time-resolved electron diffraction (TRED). Three types of experimental schemes have been developed at our lab. The experimental complex includes (i) 20-keV table-top apparatus for TRED, (ii) 75-keV ultrafast transmission electron microscope and (iii) lensless table-top device for femtosecond electron diffraction. The obtained experimental results are presented.
