Abstract: Peculiarities of the dynamics of multicharged ion plasma in extended longitudinal low-inductance high-current discharge with a power supply system based on a high-voltage generator and transmission line have been analyzed. It is shown that, using power supply systems of this type, it is possible to manage stepwise compression and heating of plasma, which provides additional possibilities in programming the physical and spectroscopic characteristics of plasma, including its ion composition.

Keywords: multicharged ion plasma, high-current radiative $Z$-discharge, nonequilibrium ion plasma composition, recombination-nonequilibrium plasma.
