Autonomous Magnetoexplosive Generator of Megavolt, 100 NS Pulses
Abstract
Here we present the results of the work carried out at different stages aimed at the development of autonomous magnetocumulative generators having 100 ns megavolt pulses. This generator is meant to replace the PIRIT-01 stationary facility by a magnetocumulative energy source. Using a generator with permanent magnets as a source of initial energy and multiplying this energy by a cascade of magnetoexplosive generators allows 100 kJ of energy accumulation in a contour. The generator that has a permanent magnet does not need an additional energy source for its operation. It is convenient to operate and is always available for service. Shortening the MC generator current pulse up to 1 μs is implemented using a high-voltage explosive driven opening switch. In the first sharpening cascade, the voltage increases up to 500 kV. Further shortening of the current pulse duration up to 100 ns and the voltage rise up to 1 MV are performed using plasma opening switches according to the two-stage formation scheme. Such a scheme allows the decrease of electric field strength on the insulator surface and the use of magnetic insulation in the high-voltage section of the facility.
