Materials Changes Taking Place During the Opening of Exploding Foil Switches

Abstract

Exploding foil .switches used to couple very large amounts of stored energy to impulsively driven loads seem to attain a limit in the rapidity at which they open. A materials science analyses of the changes which take place during the opening of copper and aluminum foil fuses, which use 100 glass beads as the quenching medium was conducted. A suggested sequence of events which takes place in SHIVA opening switches which interrupt current from 45 KJ of stored energy during the 200 n seconds required to open these switches, is proposed.
