Imploding barrel initiator and related methods

A method of designing and manufacturing an explosive device comprising:

• providing a first substrate formed with a non-electrically conductive material formed with a first and second side as well as a first, second, and third aperture through said substrate from said first to said second side, wherein said second aperture is formed in a tapering shape where one end is larger than another end;
• providing a first metallization layer formed between said first and second apertures on said first side;
• providing a second metallization layer formed between said second and third apertures on said second side;
• providing and forming an adhesion layer formed on a wall section defined by said second aperture from said first to said second side;
• providing and forming a third metallization layer formed on said adhesion layer, wherein said third metallization is electrically coupled with said first and second metallization layers;
• providing and forming a first explosive disposed within said second aperture from said first side to said second side, wherein said first explosive is any explosive having an equal or lower sensitivity to shock than PETN;
• providing and forming a second explosive positioned on said first side and positioned over said second aperture, wherein said second explosive is formed with a position in proximity or contact with said first explosive;
• and
• providing a second substrate formed, coupled with, and disposed on said second side of said first substrate, said second substrate is formed with a material and coupled with said first substrate that is configured to confine a detonation of said first explosive within said second aperture no less than a first force produced by detonation of said first explosive, said second substrate is further formed with a fourth and fifth aperture that align with said first and third apertures;
• wherein said first and second apertures are formed with a conductive section operable to receive an electric current up to a first predetermined level and also to mechanically coupled said first substrate to another structure;
• wherein said second aperture is formed with a diameter no smaller than a critical diameter of said first explosive required to sustain detonation of said first explosive;
• wherein said third metallization layer is formed with a width determined based on energy required to turn said third metallization layer into a plasma sufficient to create said first shock or energy level;
• wherein said first and second metallization layers are at least one hundred times thicker than said third metallization layer.
