Triggered spark gaps share many similarities with other gas-filled tubes such as thyratrons, krytrons, ignitrons, and crossatrons. Triggered vacuum gaps, or sprytrons, resemble triggered spark gaps both in appearance and construction but rely on a different operating principle. A triggered vacuum gap consists of three electrodes in an airtight ...
The krytron is a development of the triggered spark gaps and thyratrons originally developed for radar transmitters during World War II. The gas used in krytrons is hydrogen; [2] noble gases (usually krypton), or a Penning mixture can also be used. [3]
Consequently, the second gap breaks down to add the third capacitor to the "stack", and the process continues to sequentially break down all of the gaps. This process of the spark gaps connecting the capacitors in series to create the high voltage is called erection. The last gap connects the output of the series "stack" of capacitors to the load.
An air-gap flash type, where the flash gap itself contains a trigger electrode and acts as a switch, is a form of a trigatron with the same dual function. Trigatrons are often enclosed in resin-impregnated loose-knit fabric "socks", to contain fragments if the device explodes due to internal overpressure.
A spark on a spark plug Lightning is a natural example of an electric spark. An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.
Also, D. Bradley, J. Higgins, M. Key, and S. Majumdar realized a TLP-based laser-triggered spark gap for kilovolt pulses of accurately variable timing in 1969. For investigation of ESD and electrical-overstress (EOS) effects a measurement system using a TLP generator has been introduced first by T. Maloney and N. Khurana in 1985. Since then ...

Static triggered spark gap: Commercial and industrial circuits often apply a DC voltage from a power supply to charge the capacitor, and use high-voltage pulses generated by an oscillator applied to a triggering electrode to trigger the spark. [7] [23] This allows control of the spark rate and exciting voltage.
