A detonator, sometimes called a blasting cap in the US, is a small sensitive device used to provoke a larger, more powerful but relatively insensitive secondary explosive of an explosive device used in commercial mining, excavation, demolition, etc.
The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
Detonation (from Latin detonare 'to thunder down/forth') [1] is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it.
DETONATOR definition: 1. a small amount of explosive in a bomb that explodes first and causes a larger explosion, or an…. Learn more.
Apr 8, 2024 · The meaning of DETONATOR is a device or small quantity of explosive used for detonating a high explosive.
Blasting cap, device that initiates the detonation of a charge of a high explosive by subjecting it to percussion by a shock wave. In strict usage, the term detonator refers to an easily ignited low explosive that produces the shock wave, and the term primer, or priming composition, denotes a.
Jun 11, 2023 · The detonator is a detonating device that is equipped with priming in the tube and can directly detonate the explosive. According to the way of detonation, detonators can be divided into the flame detonator, electric detonator, detonating cord detonator, and electronic (digital) detonators.
Jul 19, 2023 · Although exploding bridgewire detonators are still made and used for some purposes, the Lab has developed new detonator designs over the years. One new detonator is called a chip slapper.
Jul 17, 2019 · (a) The detonator. The exploding bridge-wire (EBW) detonator was invented in Los Alamos towards the end of the Second World War . The aim was to create a safe detonator with highly repeatable functioning time (less than 1 μs) coupled to a powerful explosive output booster.
Jul 11, 2017 · To overcome these major challenges, Los Alamos scientists and engineers developed new innovations in the field of electronics. Three essential innovations for the implosion design’s success were Exploding Bridgewire Detonators, the Spark Gap Switch, and Composition B explosive lenses.
