A plasma accelerator was investigated, which consists of two coaxial cylinders of stainless steel. Clots obtained from this source were investigated with the aid of a mass-spectrograph with an electric field intensity of 20 kv. The experimental results show that the density and velocity of plasma clots are not at all affected by the material of the electrodes, nor by the parameters of the discharge stakes with the exception of capacitor capacities. The change in geometric dimensions e. g., changes in length of central electrode actually affects the velocity, number of fast ions and magnitude of total energy of the clot. The results of this investigation confirm the conclusion that the mechanism of accelerating the clots in a coaxial source differs from the one proposed up to this time.
