With the double plasma device in the vacuum chamber at the Tokai University, we carried out a laboratory plasma experiment to generate the electric double layers and their associated fast energetic electron beams. The result shows that a formation of double layers depends sensitively on the electric potential applied between the source and target plasmas. A clear double layer with about 20V potential difference is created when the electric potential of 40V is applied between the source and the target. However, when the electric potential less than 40V is applied, any clear double layer is not formed. A measurement on a velocity distribution of electrons in the generated double layers reveals a clear existence of trapped and free electrons, and the free electrons are proved to be accelerated in proportion to the potential of the generated double layers.
