A measurement of the first Townsend coefficient in argon based mixtures at high fields
Abstract
We have measured the first Townsend coefficient α at high fields, in pure hydrocarbons and their mixtures with argon using a parallel plate chamber at various pressures. This is in order to understand the operating characteristics for high localization accuracy drift chambers operating in proportional and streamer regimes.
