Choice of operation conditions and plasma parameters of a magnetoplasma compressor

Results of optic and spectroscopic investigations into compression plasma flow of magnetoplasma compressor (MPC) are presented. MPC has a compact geometry with valve (pulsed) operating gas (hydrogen) feeding. Flow formation dynamics in such a MPC is studied. Rate, concentration of electrons and plasma temperature are determined. It is shown that the dependence of maximum discharge current value obtained on the mass operating gas flow rate allows one to chose the optimal conditions for MPC operation. Relatively high plasma flow parameters with the impurity quantity minimal for such systems, are relalized under the conditions mentioned
