Electron avalanche
An
electron avalanche
is a process in which a number of
free electrons
in a
transmission medium
are subjected to strong acceleration by an
electric field
and subsequently collide with other atoms of the medium, thereby
ionizing
them (
impact ionization
). This releases additional electrons which accelerate and collide with further atoms, releasing more electrons—a
chain reaction
. In a
gas
, this causes the affected region to become an
electrically conductive
plasma
.
