The Commutation of the Energy Produced by a Helical Explosive Generator Using Exploding Foils
The generator has an outer diameter of 200 mm, is 800 mm long and is filled with 5 kg of a high explosive. So as the energy rise time in the load be of the order of a few microseconds which is requested in various applications, a switching is included, consisting mainly of the opening of the circuit through the vaporization of a thin foil (100μ.m). In the 60 nH load the current intensity rises to 2 MA in 6.5 μsec. Five identical shots have been made. All were very satisfactory. The same combination generator and switch have been successfully used with a plasma Focus device protected from the exploding generator by a concrete building. The present experiments at the level of 100 kJ in 60 nH with risetimes of a few microseconds show the reliability and reproductibility of the devices developed.
