Advances in Explosively Formed Fuse Opening Switches
Abstract
We are pursuing the development of Explosively Formed Fuses along two separate lines. One design, has now been demonstrated to conduct a 9.5 MA 350 microsecond risetime pulse and interrupt it in 1.2 micros. Ultimately, this design should operate at up to 15 MA with 20-nH loads. A second design with enhanced performance characteristics is being examined and will be tested on a small scale. This design includes opening switch inductance as part of the inductive store and, as a result, should have shorter pulse transfer times and should be able to be scaled to handle currents up to ~25 MA with 20 nH loads.
