RESEARCH ON THE ELECTROSTATIC GENERATION AND ACCELERATION OF SUBMICRON- SIZE PARTICLES
Abstract
Research involved in generating submicron-size positively charged liquid droplets is described. The droplets formed may be either liquid metal, or organic fluids. An analysis is developed to indicate the relationship between particle size and the parameters of field emission and surface tension. Charge/ mass ratios were obtained. Charge/mass distributions are shown for both metals and organic fluids. Although ions were often found, particularly with the metal fluids, narrow peak distributions of charge/mass could be obtained with no appreciable number of ions when using the organic liquids. The effect upon the charge/mass peak of the mass flow rate and the potential of the point emitter is demonstrated. The efficiency of an ion engine as a function of charge/mass distribution about a peak was evaluated for several typical curves.
