In this study, in order to apply ultrashort pulsed electron beam techniques to electron inelastic scattering experiments, we have developed a new pulsed electron gun having a small kinetic energy distribution, while keeping its duration applicable to a real-time observation of chemical reactions. As a result, the developed electron gun is successful in producing electron pulses whose energy width is less than electronic excitation energies(c. a. 5 eV)of typical simple molecules. The electron gun has shown the expected performance in its intensity as well as in the energy width.
