Claims
- What is claimed is: 1. An explosive train, comprising: a fixed initiator element comprising a base layer, an unreacted metal substrate layer and a primary explosive layer; an acceptor explosive; and a mobile slider element being movable between an unarmed position that is out of line with the fixed initiator element and the acceptor explosive and an armed position that is in line with the fixed initiator element and the acceptor explosive, wherein the mobile slider element is comprised of a base layer, an unreacted metal substrate layer and a primary explosive layer, the base layer including a barrel formed therein, wherein an open end of the barrel is adjacent the acceptor explosive when the mobile slider element is in the armed position, and wherein the primary explosive layer of the mobile slider element is adjacent the primary explosive layer of the fixed initiator element when the mobile slider element is in the armed position. 2. The explosive train of claim 1, wherein a combined amount of primary explosive in the mobile slider element and the fixed initiator element is no greater than about ten milligrams. 3. The explosive train of claim 1, wherein a combined size of the mobile slider element and the fixed initiator element is no greater than about one cubic millimeter. 4. An explosive train, comprising: a fixed initiator element comprising a base layer, an unreacted metal substrate layer and a primary explosive layer; an acceptor explosive; and a mobile slider element being movable between an unarmed position that is remote from the fixed initiator element and the acceptor explosive and an armed position that is adjacent the fixed initiator element and the acceptor explosive, wherein the mobile slider element is comprised of a base layer, an unreacted metal substrate layer and a generally wedge shaped primary explosive layer, the base layer includes a barrel formed therein, wherein an open end of the barrel is adjacent the acceptor explosive when the mobile slider element is in the armed position, and wherein a narrow end of the generally wedge shaped primary explosive layer of the mobile slider element is adjacent an end of the primary explosive layer of the fixed initiator element when the mobile slider element is in the armed position. 5. The explosive train of claim 4, wherein a combined amount of primary explosive in the mobile slider element and the fixed initiator element is no greater than about ten milligrams. 6. The explosive train of claim 4, wherein a combined size of the mobile slider element and the fixed initiator element is no greater than about one cubic millimeter.
