Summary edit

Description
English: Visualisation of an electron avalanche, also known as a Townsend discharge or a townsend avalanche. The applied electric field accelerates free electrons to collide with other atoms and release further electrons, causing an avalanche. This phenomena is used in a variety of radiation and particle detection instruments where the gas multiplication effect is used. This includes Geiger-Muller counters and Proportional counters.
