Investigation of the ionization process for nitrogen and formation of the multiply charged ions in the channel of plasma accelerator

Research of the ionizing gas flows and the process of ionization of nitrogen in the channel of the quasi-steady plasma accelerator were carried out. The model is based on the modified MHD equations for a medium consisting of atoms, electrons and multiply charged ions. The numerical model includes the electrical conductivity and thermal conductivity of a multicomponent medium, the energy loss for radiation, and a system of the ionization equilibrium equations in the presence of multiply charged ions with the different ionization multiplicities.
