Multiplexing Creation of a Compression Zone in the Plasma Steam MPC under Different Initial Conditions

Section: Plasmas and Gases
Original Author's Text: English

Abstract: The analysis of fundamental properties of the compression zone in the self-compressed plasma streams generated by a magnetoplasma compressor (MPC) is carried out. The main attention is attended to the research of the dependences of basic plasma parameters in a compressed plasma stream depending on the initial conditions. It has been shown experimentally that the reduction of the initial concentration of a working gas leads to an increase of the plasma density in the compression zone. The detailed studies of the spatial distributions of currents in the plasma flows are fulfilled for different initial concentrations of a substance in the accelerating channel of MPC. Under the experiment conditions, it is found that a decrease of the initial concentration of a working gas leads to the displacement of the currents from the compression zone.

Key words: plasma dynamics, magnetoplasma compressor, compression zone.
