High-performance, high-current fuses for flux compression generator driven inductive store power conditioning applications
Large-scale helical flux compression generators deliver energies in the range of 10--50 MJ in economical, flexible packages for powering a variety of plasma and electron beam experiments. While conventional, end-detonating, helical generators are simple and reliable, they have the disadvantage of delivering their energy over long timescales, up to 400--500 ..mu..s, and at relatively low output voltages. Many experiments require faster risetimes than can be delivered by a helical FCG directly, and inductive systems utilizing high current interrupting switches can be employed to match generator performance to load requirements. For this experiment, a 15-MJ class helical flux compression generator was selected as the primary energy source. This flux compressor is a modification of a design proposed by Pavlovski in 1979 and used routinely in Los Alamos programs. The generator consists of a multiple conductor, multiple pitch, helical stator and a hollow copper armature containing a 60-kg charge of PBX 9501 high explosive (HE) which is initiated by a small plane wave lens at the end opposite the output. 8 refs., 12 figs.
