first townsend coefficient
1Townsend coefficient — The first Townsend coefficient ( α ), also known as first Townsend avalanche coefficient is a term used in an ionization process where there is a possibility of secondary ionization because the primary ionization electrons gain sufficient energy… …
2Townsend discharge — The Townsend discharge is a gas ionization process where an initially very small amount of free electrons, accelerated by a sufficiently strong electric field, give rise to electrical conduction through a gas by avalanche multiplication: when the …
3Raether limit — The Raether limit is the physical limiting value of the multiplication factor (M) or gas gain in an ionization avalanche process (Townsend avalanche). Even though, theoretically, it seems as if M can increase without limit (exponentially),… …
