The measurements of the spatial distribution of electric currents in the plasma flow, the plasma density distribution, both in time and along the flow and the dependence of velocity of the separate layers of the flow along the axis of the system were fulfilled. The analysis of the spatial distribution of the electromagnetic force in the flow was performed. It is shown that plasma flow slowed when approaching the compression zone, and after its passage is accelerating. The velocity of the plasma flow decreases from the value v = 200-300 km / s at the output of the MPC till v <10 km / s in the region of maximum compression. Velocity subsequently increased again to 100 km / s at a distance of 15-17 cm from the edge of the MPC . In some modes of the MPC operation, it was registered displacement of the magnetic field from compression zone and the creation of toroidal vortex of the electric current in the plasma flow after passing the area of compression. On the base of the comparative analysis of the energy characteristics of the discharge in the MPC, and generated plasma flows it was shown that regardless of the atomic mass of the working gas energy that is introduced into the discharge and the energy of plasma flow, increases with decreasing pressure working gas in the chamber. Thus the efficiency of the MPC increases. It was found that in conditions of constant mass flow in the accelerating channel MPC energy that is introduced into the discharge is almost independent of the atomic mass of the working substance. On the bases of this analysis, the new approach to high-power plasma devices quasi dynamic actions was developed for the solution many fundamental and applied issues.
