An electron avalanche is a process in which a number of free electrons in a medium (usually a gas) are subjected to strong acceleration by an electric field, and subsequently collide with other atoms of the medium and thereby ionize them in a process called impact ionization. This releases additional electrons which are themselves accelerated and collide with further atoms, releasing more electrons, in a chain reaction.
