Measurements of the enclosed electric power at compression of wire arrays of installation “Angara-5-1”

Results of experimental studying of cylindrical multiwire arrays compression in Z-pinch discharge at a current up to 3.5 MA are submitted. The purpose of work has consisted in finding-out of influence of initial characteristics of arrays on efficiency of electric energy transfer from the generator of high-voltage pulses of a current in energy of plasma. The power and duration of X-ray pulse were used as indicators of efficiency of energy transfer from generator to plasma at stagnation. For analysis of experiments modified 0-D system of equations was applied. Application of the modified system of the equations allows predicting prominent features of experimental profiles of a current and a voltage, the minimal size of pinch and a characteristic time scale of its stagnation. Comparison of the electric power enclosed in Z-pinch with the power of x-ray output is carried out. It is shown, that during stagnation there is an effective plasma movement braking which correlates with increase of output x-ray power. Peaks of hard X-ray with energy of quanta more 50 keV which are detained relatively to peak of soft X-ray were observed. The evidence of development of accompanying phenomenon which can be connected to development of processes of conversion of magnetic energy in energy of plasma is revealed have been registered. Possibility of output X-ray power profiling by means of application induced longitudinal magnetic field and mix substance arrays is observed.
