Negative ion drift velocity and longitudinal diffusion in mixtures of carbon disulfide and methane

Negative ion drift velocity and longitudinal diffusion have been measured for gas mixtures of carbon disulfide (CS2) and methane (CH4). Measurements were made as a function of total pressure, CS2 partial pressure and electric field. Constant mobility and thermal-limit longitudinal diffusion are obse...

Zusammenfassung:Negative ion drift velocity and longitudinal diffusion have been measured for gas mixtures of carbon disulfide (CS2) and methane (CH4). Measurements were made as a function of total pressure, CS2 partial pressure and electric field. Constant mobility and thermal-limit longitudinal diffusion are observed for all gas mixtures tested. Gas gain for some of the mixtures is also included.
