A miniaturized bulkhead with a barrier member having a thickness in the range of less than 0.05 inches thick for separating explosive charges on opposites sides. The miniaturized bulkhead is manufactured from an age hardened nickel-base alloy. First and second cavities are separated by the barrier member integral with the initiator body. The first cavity is filled with an explosive donor charge, and the second cavity is filled with an explosive acceptor charge. The composition of the age hardened nickelbase alloy includes nickel in the range of 50-55 per...


[ The embodiments of an invention in which an exclusive property or right is claimed are defined as follows:] [1.] A miniaturized bulkhead with a barrier member for separating explosive charges on opposites sides thereof, said miniaturized bulkhead comprising:an explosive donor charge;an explosive acceptor charge;an initiator body constructed of substantially an age hardened nickel-base alloy, said initiator body including first and second cavities separated by a barrier member integral with said initiator body, said first cavity substantially filled wit...
