Summary

Description
English: Visualisation of discrete Townsend avalanches in a proportional counter
Suomi: Verrannollisuuslaskurin toimintaperiaate. Ionisoiva hiukkanen lävistää kammion irroittaen kaasusta elektroneja. Elektroni kiitä kohti positiivisesti varattua anodilankaa. Riittävän lähellä anodilankaa voimakas sähkökenttä kiihdyttää elektroneja siten, että nämä törmäilevät kaasumolekyyleihin irrottaen lisää elektroneja muodostaen elektronivyöryn.
