plasma jet

A plasma jet is a stream of very hot, ionized plasma, or a device that creates such a stream. Plasmas are often formed artificially by applying heat or electric fields to gases, as they require extremely high temperatures (around 10,000 K) for ionization.12

Plasma jets have various applications, including in chemical and metallurgical processes. They can also be used in arc discharges, which are high-density plasmas used for welding, electronic switching, and high-temperature chemistry. While many plasma applications are still in development, particularly in power generation through fusion reactors, they also play a role in everyday technologies like neon signs and fluorescent lamps.3
