Line 4:
There are several ways to cause [[ionization]]:
collisions of energetic particles, strong electric fields acting on bond
[[electron]]s, or [[ionizing radiation]]. The [[kinetic energy]] for ionizing 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.
If at least as many [[charge carrier]]s are created per time unit as
recombine, the plasma can be sustained.
