Integral model of a pulse coaxial plasma gun

The integral model of a pulse coaxial plasma gun is described. The main characteristic feature of the model is registration of the non-uniform working gas distribution and the shifting of the place of the primary accelerator breakdown. It is shown that the model describes well the dependence of the profile of the discharge current curve on the accelerator gas inventory as well as the velocity of the current front and the dynamics of the energy transfer from the accelerator battery into plasma. From the analysis of the results of the numerical calculations it is clear that to achieve optimal results it is necessary to coordinate the gas accelerator inventory in every specific case with its electrotechnical parameters
