Summary: | A device is being considered consisting of a helical explosive magnetic generator, a cascade of explosive and electroexplosive opening switches. This device serves to obtain a single pulse or a group of voltage pulses with the amplitude of up to 1 MV and a duration of several hundred nanoseconds in loads having an impedance of 1-15 Ohm. The interval between the pulses is equal to several microseconds. The electroexplosive cascade contains the given (in accordance with a required number of pulses) number of steps of conductor having different cross-sections and lengths. Amplitude, shape of pulses and the interval between them may be within certain limits changed by the way of picking out the conversion cascades' design parameters. The authors have modelled the operation of the exit cascade of the considered device powered by a capacitor facility. Copper wire, having several parts of different cross-sections, was used as the electroexplosive opening switch. Oscillograms with two and three consecutive pulses with an amplitude of about 550 kV and a duration of less than 500 ns were obtained. The interval between the pulses was about 2 /spl mu/s. |
