Multimegajoule Pulsed Power Generation from a Reusable Compressed Magnetic Field Device
A pulsed power system is described which is potentially capable of producing multimegajoule pulses with millisecond rise time and repetition rates of more than one per second. A metallic piston is driven by gas combustion through axially aligned coils which are originally energized with relatively small magnetic energy. Experimental results are presented for a pulse generator of this kind which utilized a piston of 20 MJ kinetic energy, and comparison is made with predictions of a numerical model.
