The EBW was invented by Luis Alvarez and Lawrence Johnston for the Fat Man–type bombs of the Manhattan Project, during their work in Los Alamos National Laboratory.The Fat Man Model 1773 EBW detonators used an unusual, high reliability detonator system with two EBW "horns" attached to a single booster charge, which then fired each of the 32 explosive lens units.
Non-electric detonators are typically stab or pyrotechnic while electric are typically "hot wire" (low voltage), exploding bridge wire (high voltage) or explosive foil (very high voltage). [2] [3] The original electric detonators invented in 1875 independently by Julius Smith and Perry Gardiner used mercury fulminate as the primary explosive.
The explosive can be pressed to higher density; Very insensitive explosives can be initiated directly. In a variant called laser detonator the vaporization can be caused by a high-power laser pulse delivered over-the-air or coupled by an optical fiber; this is reportedly used as a safety detonator in some mining operations and quarries.
It’s considered a high explosive material, meaning it won’t detonate without a primary explosion occurring near it — initiated by what’s known as a blasting cap or detonator.
High explosives (HE, or high-order explosives) are explosive materials that detonate, meaning that the explosive shock front passes through the material at a supersonic speed. High explosives detonate with explosive velocity of about 3–9 kilometres per second (9,800–29,500 ft/s). For instance, TNT has a detonation (burn) rate of ...
In the two-point linear implosion, the nuclear fuel is cast into a solid shape and placed within the center of a cylinder of high explosive. Detonators are placed at either end of the explosive cylinder, and a plate-like insert, or shaper, is placed in the explosive just inside the detonators. When the detonators are fired, the initial ...
The US Army vet rigged the explosives with makeshift remote detonators he put together from readily available materials, including electric matches, or “hobby switches.” ...
The explosive triggering sequence or the explosive train essentially consists of an 'initiator', an 'intermediary' and the 'high explosive'. For example, a match will not cause plastic explosive to explode, but it will light a fuse coupled with a blasting cap which will detonate a primary explosive that will shock a secondary high explosive and ...
