ACCELERATION OF DISCHARGE PLASMA AND THE PRODUCTION OF STRONG SHOCK WAVES IN A CHAMBER WITH COAXIAL ELECTRODES (in Russian)
Plasma acceleration by relatively continuous (one or several periods) radial discharge current interactions with concentric magnetic fields is analyzed. In addition to the acceleration, strong shock waves develop with a peculiar distribution of energy at temperatures where the constricted gas thrns into plasma. A device consisting of two coaxial cylindrically shaped electrodes in a plexiglas chamber of 2 to 5 cm internal diameter and 50 to 90 cm long, with 150, 600, and 2400 mu f capacity and initial potential of 5 to 6 kw is described. The results confirmed the efficiency of acceleration by this method. The shock wave and plasma velccities increased 1.5 to 2 fold in comparison to acceleration under similar conditions but without coaxial electrdes. Velocities of 30 to 80 km/sec were obtained at an initial nir pressure of 0.7 to 0.02 mm mercury with an initial potential of 5 kw. (R.V.J.)
