PARTICLE GROWTH IN THE IONIC NUCLEATION CONDENSATION COLLOIDAL ION SOURCE,

Abstract

This analytical treatment of the ionic nucleation condensation colloidal ion source examines the processes involved in the formation and growth of ionic nuclei under controlled conditions. The analysis of the condensation nuclei considers the formation of neutral nuclei, which must be prevented, and the formation of the required ionic nuclei. Several theoretical concepts of nucleation are examined. Since the growth of the nuclei to colloids of a size suitable for use in electrostatic propulsion engines involves a considerable release of heat, the growth process is analyzed on the basis of three different models for the dissipation of the heat of condensation. The conditions and resultant properties are calculated for a mixed propellant flow of cadmium and hydrogen on the basis of these three models. (Author)
