Research of Dielectric Materials.
Abstract
Phase I of this work was concerned with electron impact ionization and attachment in polyatomic gases. These processes were examined using a mass spectrometer operating with a retarding potential difference electron source. Ionization and attachment coefficients were measured using an electron swarm or Townsend technique. Results were obtained principally with perfluorocarbon gases, many of which are of interest for use as high dielectric strength gases. In Phase II, studies of the chemical degradation of materials under the action of corona were continued. Along with continuing the studies on weight loss in Mylar, similar investigations were made on 'H' film at the request of AF materials Laboratory, Research and Technology Division. The chemical effects of different types of corona discharges, distinguished earlier, were studied on model compounds. By the use of d-c voltages it was possible to compare damage caused by positive ion and electron bombardment. (Author)
