Abstract
In work presented the results of researches of plasma flow formation and propagate in the electrodynamics pulsed gun. Experimental researches carried out on the basis of pulse plasma accelerator CPU-30 with a coaxial symmetric geometry electrodes. It was shown, that structure of the flow significantly depends on initial operating pressure of working gas, and specify for “continuously filled” regime. The data on dynamics of plasma acceleration, obtained in previous studies was refined. The role of plasma internal electric field and acceleration peculiarities on differ pressure of initial gas are discuss.
