Line 2:

of a medium. There are several ways to cause [[ionisation]]:

collisions of energetic particles, strong electric fields acting on bond

electrons[[electron]]s, or ionising radiation. The [[kinetic energy]] for ionising collisions

may come from the heat of chemical or nuclear reactions of the medium, as in

[[flame]]s, for instance. Alternatively, already released charged particles may be

accelerated by [[electric fieldsfield]]s, generated electricallyelectromagnetically or by radiation fields.

If at least as many [[charge carrierscarrier]]s are created per time unit as

recombine, the [[plasma]] can be sustained.

Plasma excitation by [[electromagnetic fieldsfield]]s can be classified according to
