The current mode of pulsed power generation in moving magnet systems

Results are presented of investigations of the generation of high-current pulses in moving magnet generators designed as an open ferromagnetic circuit. The experimental study was performed with the use of a light gas gun. The magnetic projectiles were ferromagnetic cylinders having 2.54-cm diameters. Data are given for the amplitude of high current pulses and power in the load for different designs of the devices, the effect of various windings on the pulse-generating coils, and different types of loads. It has been shown that with velocities of the magnetic projectiles of 200-300 m/s, the peak current of the pulses produced by the generators reach kiloamperes.
