High-voltage detonator

A high-voltage detonator (HDV) based on CP was also developed for the Titan IV launch vehicle [23]. The production of CP had been discontinued due to its toxicity [21]. 

For detonators to be used where electrostatic charges may occur, it is desirable to prevent sparking from the fusehead to the case, should a high voltage be generated on the leading wires. For this purpose, an insulating sheath is inserted, either into the detonator tube or else immediately around the fusehead.

Experimentally obtained data for detonation by direct initiation energy in hydrogen -i- air mixtures (with equivalence ratios 0.75-0.5) have been in the range between 10 and 1,000 kJ. The ignition energy is several milh-Joules. A high-voltage... 

X UNIT. The high-voltage, capacitor-based system developed by the Manhattan Project to fire the Fat Man nuclear weapon detonators simultaneously. The design of Fat Man involved an implosion that initiated a fission chain reaction. Precise control of the timing and sequence of detonation events was essential to ensure proper functioning of this design. 

Ionisation probes. The operating principle of the ionisation probes is based on the fact that detonation products behind the detonation front are highly ionised, which makes them capable of conducting electric current. Thus, the arrival of the detonation wave at an ionisation prote (vsiiich is actually an electrical switch) enables the closure of the electric circuit. That allows a capacitor to discharge, and the associated voltage signal is used to start/stop the counting assembly of the electric counter.
