Line 2:

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

collisions of energetic particles, strong electric fields acting on bond

[[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 field]]s, generated electromagnetically or by radiation fields.

accelerated by [[electric field]]s, generated electromagnetically or by radiation fields.

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

recombine, the plasma can be sustained.

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