Ignition occurs when the heat produced by a reaction becomes sufficient to sustain a chemical reaction. The sudden change from a cold
gas to a hot
plasma in a plasma source is also called ignition.Other uses of ignition include:in
chemistry, it refers to heating a material to the point that it spontaneously
combusts, or until it ceases to lose mass.in
nuclear fusion, it refers to the conditions under which a plasma can be maintained by fusion reactions without external energy input.in
semiconductor processing, ignition is the process of starting up a plasma generator. In
DC plasma systems, this involves a transition from voltaic arcing to sustained and delocalized plasma generation.an
ignition system is a method for activating and controlling the combustion of fuel in an internal combustion engine, often through the use of a key
