Plasma flow formation in a pulse plasma accelerator in continuous filling regime

Distribution of energy density of a plasma flow in the KPU-30 pulse coaxial accelerator at continuous gas filling has been investigated. The influence of discharge parameters on energy density at various pressures of the working gas is demonstrated. It is shown that the maximal plasma energy occurs in a pressure range of 0.02–0.05 torr. Distributions of energy density in the axial and radial directions are obtained. The focus point of the plasma flow is found and the plasma flow energy density at this point is measured.
