Ionization Instability
An ionization instability is any one of a category of Plasma (physics), plasma Plasma stability, instabilities which is mediated by electron-impact ionization. In the most general sense, an ionization instability occurs from a feedback effect, when electrons produced by ionization go on to produce still more electrons through ionization in a self-reinforcing way. Ionization instabilities have been seen in such plasma physics apparatus as Glow discharge, glow discharges, Penning discharges, Magnetic nozzle, magnetic nozzles, and MHD Generator, MHD generators. Ionization instabilities may occur in magnetized or unmagnetized plasma. They occur mostly when the plasma is relatively cold and only partially ionized, so that there is a lot of neutral gas mixed in with the plasma. In a glow discharge A glow discharge is a plasma-containing apparatus in which the plasma is formed by a large voltage placed across a rarefied gas. Glow discharges are used for electric lighting and materials ...

Plasma (physics)
Plasma ()πλάσμα
, Henry George Liddell, Robert Scott, ''A Greek English Lexicon'', on Perseus is one of the four fundamental states of matter. It contains a significant portion of charged particles – ions and/or s. The presence of these charged particles is what primarily sets plasma apart from the other fundamental states of matter. It is the most abundant form of ordi ...
