Abstract: A detonator with a base portion including opposing electrical leads; an exploding foil initiator on the base portion, the exploding foil initiator including two conductive lands separated by a bridge portion therebetween; and a connecting barrel of a predetermined thickness on the exploding foil initiator for optimizing the spacing between the exploding foil initiator and an explosive charge and for robustly interconnecting the lands of the exploding foil initiator with the electrical leads of the base portion.

Abstract: A detonator with a base portion including a header wall terminating in a support surface; an initiator on the support surface; an explosive charge spaced from the initiator; and a cap having an interior top surface and an enclosure wall extending downward from the interior top surface and surrounding the initiator and the explosive charge. The wall terminates in a rim secured at a location along the header wall corresponding to the thickness of the initiator, the spacing between the initiator and the explosive charge, and the thickness of the explosive charge thereby ensuring that the explosive charge is in communication with the interior top surface of the cap.

Abstract: A hermetically sealed laser actuator/detonator includes a housing with an orifice for receiving a laser beam and a chamber having a first lens, a compression sealing material at least partially about the first lens, and an energetic material optically coupled to the first lens.
