Superpower Disk Explosive Magnetic Generators of Electromagnetic Energy for High-Energy Densities Research

Multimodule disk explosive magnetic generators (DEMGs) of microsecond pulses of electromagnetic energy up to hundreds of megajoules, based on the internal explosive energy into electromagnetic energy conversion (magnetic flux compression), are reviewed. Fundamentals of the DEMG operation are outlined. Conventional DEMGs with intricate disk profile are described in short. A numerical technique of DEMG simulations is outlined. Special attention is given to the modernized DEMGs with flat modules of different calibers. At preservation of the output characteristics of the DEMGs with profile discs, the factor of the explosive to electromagnetic energy conversion of the DEMGs with flat discs is twofold higher; such DEMGs achieve higher speeds, represent a technological advance and are less expensive.
