Abstract

A focused output detonator includes a detonator shell including detonator components, and a focuser coupled to the detonator shell. The detonator shell may include a body extending along a central axis of the detonator shell. A first open end is provided at a first end of the body, and a closed end is provided at a second end of the body. A chamber is bounded by the body and the closed end, and the detonator components are housed in the chamber. The focuser is coupled to the closed end of the detonator shell. According to an aspect, the focused output detonator is structured to focus a ballistic output of the focuser along the central axis and away from the detonator shell. According to an aspect, the focuser includes a donor charge. The focuser may include an encapsulated and hydraulically sealed donor charge.
