Abstract: A model of a disk-shaped explosive magnetic generator 400 mm in diameter with an initial energy storage capacity of about 40 MJ is considered. The generator is integrated with a cumulative current pulse shaper and is also equipped with a remote magnetodynamic interrupter. Calculations show that this generator is capable of forming current pulses with an amplitude of up to 20 MA and a rise time of about 130 ns in finiteinductance ($\sim$ 10 nH) dynamic loads. This allows rapid (for about 60 ns) compression of light (20–30 mg) liners to generate intense beams of soft X rays. Results obtained using a computational model of the magnetodynamic interrupter, which is the key component of the generator, are verified experimentally.
