RADIATION EFFECTS IN THE DIELECTRIC MATERIALS.

Abstract

Irradiation experiments to verify theories of transient radiation effects in insulators are discussed. High-energy electron, proton, and neutron irradiations of specially designed Mylar capacitors are planned. Experiments designed to measure polarization and secondary emission effects in thin-film capacitors and thin-film circuitry on sapphire substrates are described. Initial results of irradiation of Lucite samples by electrons from a 3-MeV flash x-ray machine indicated internal discharge resulting from strong nonuniform electrical fields created in the material by the radiation; also listed are other materials used in electronic equipment that are to be tested in this manner. Ion-implanted electrodes on a Mylar capacitor indicated better carrier injection characteristics than foil contacts to the same material, but some polarization effects attributable to the contacts still remained.
