  • Abstract
    In this paper, the authors present an analysis of the avalanche growth in electronegative gases, which exhibit detachment process in addition to ionization and attachment. The model is used to determine swarm parameters from a pulsed Townsend method. As an example, the swarm parameters for SF6-Xe are presented and discussed. A new swarm method for measurement of electron ionization, attachment and detachment from negative ions in SF6 and its mixtures is developed. The value of the transport coefficient of SF6-Xe is also given.
