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.
