Multi-stage flux-trapping helical flux compression generators

Summary form only given, as follows. Several types of multi-stage flux-trapping helical flux compression generators for high impedance loads are considered. Short-pulsed two-stage generators with the helix diameter of 100 mm and the initial energy of 0.7 kJ have supplied the energy up to 30 W into the 5 mcH inductive load in the time about 15 mcs. Long-pulsed two-stage generators with the initial energy of 1.5 kJ have supplied the energy up to 350 kJ into the 0.3 mcH inductive load in the time about 50 mcs. Three-stage generators produces energy of 700 kJ in the load of 0.5 mcH. Large three-stage generator with the final helix diameter of 160 mm have supplied energy up to 1.6 MJ into the 0.5 mcH inductive load. The experimental data are compared with the computer. simulation.
