1. A focused output detonator comprising:
a detonator shell comprising:
a body extending along a central axis of the detonator shell;
a first open end provided at a first end of the body;
a closed end provided at a second end of the body; and
a chamber bounded by the body and the closed end;
a focuser coupled to the closed end and extending along the central axis of the detonator shell;
an electronic circuit board;
a fuse operably coupled to electronic circuit board;
an initiator head coupled to the first open end of the body of the detonator shell, the initiator head comprising:
an initiator head housing extending in an axial direction of the detonator shell; and
a line-in terminal accessible from an exterior of the initiator head housing, wherein line-in terminal is provided on a first side of the housing in the axial direction and the line-in terminal is operably connected to the electronic circuit board;
wherein the electronic circuit board is provided in an interior space of the initiator head housing, a thickness direction of the electronic circuit board being substantially parallel with the axial direction;
the fuse is displaced from the electronic circuit board in the axial direction, and the fuse is operably connected to the electronic circuit board; and
the electronic circuit board is configured to activate the fuse in response to a control signal received at the line-in terminal;
wherein the focuser is shaped to focus a ballistic output of the focuser along the central axis and away from the detonator shell.
