Controlling the radiation characteristics of a magnetically compressed discharge of megawatt electric power

For a plasma light source based on a magnetically compressed discharge operating in a regime with a discharge-current pulse width equal to 1 s, induced by an electric power of about 1 MW, the possibilities are investigated of forming the time dependence and energy characteristics of radiation supplied from a network thyristor rectifier with an output voltage of about 500 V and a discharge current of up to 6000 A. It is shown that increasing the fraction of easily ionizable elements (Na, Ca, La) in the composition of the plasma-forming material increases the radiant exitance of the plasma radiator. The optimum induction of the compressing magnetic field is found.
