Abstract:
A fireset for a low energy exploding foil initiator (LEEFI), the fireset comprising:a first capacitor for storing a level of electrical energy sufficient to fire the LEEFI, said first capacitor being in electrical communication with said LEEFI;second, third, and fourth capacitors in electrical communication with said first capacitor for storing lesser levels of energy than said first capacitor;trigger means for directing a pulse of electrical energy into said fireset;an integrated circuit to which said pulse of electrical energy is directed and which is adapted to invert said pulse and to dump said third and fourth capacitors;a first metal oxide semi-conductor fill effect transistor (MOSFET) switch turned on by said integrated circuit and the dumping of said third and fourth capacitors, said first MOSFET switch being operable to dump said second capacitor; anda second MOSFET through which said second capacitor is dumped, operative to discharge said first capacitor through said second MOSFET, to fire the LEEFI.
