Abstract:

This report describes a comprehensive set of measurements of electron, negative-ion, and positive-ion mobilities together with attachment and ionization rate coefficients for dry air and mixtures of dry air with water vapor. These measurements were made for values of EN the ratio of electric field to gas density ranging from about 10 to the -22nd power Vm2 to about 3x10 to the -19th power Vm2. This range of EN corresponds to values of electric field at atmospheric pressure from about 10 thousand to 10 million Vm and covers values of electron mean energy from near thermal to values well above the onset of impact ionization. Keywords Air chemistry Drift tube Ionization coefficient Mobility Swarm parameters.
