Air Chemistry Measurements 2
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 E/N (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 E/N corresponds to values of electric field at atmospheric pressure from about 10 thousand to 10 million V/m 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.
