AN EXPERIMENTAL STUDY OF THE BEHAVIOR OF LARGE NEGATIVE IONS.

Abstract : Electron attachment properties and mobility studies of ions, formed in high molecular weight fluorocarbon compounds and drifting through a light medium, were made using a drift tube experiment. The reduced mobilities are found to be lower than the predictions of the small ion theory of Langevin. Using the experimentally determined mobility, the stage efficiency, and pressure ratios for a linear EHD device were evaluated when the device uses ions formed in Freon E-3. (Author)
