Advances in explosively formed fuse opening switches

PDF Version Also Available for Download.

Description

The development of Explosively Formed Fuses along two separate lines is discussed. One design, which has previously been demonstrated to conduct a 9.5 MA 350 ..mu..s risetime pulse and interrupt it in 1.2 ..mu..s. This scaled up 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 ... continued below
