Changes in the properties of dielectric material T-8000 produced by irradiation with electrons and protons

In studying the dielectric properties of material T-8000, a difference was discovered in the effects of electron and proton irradiation on dielectric permeability () and dielectric loss angle tangent (tan ). It is assumed that upon irradiation with protons having higher energy (4.25 MeV) the processes of titanium, zirconate, and barium ion displacement occur with greater probability than upon irradiation with electrons whose energy does not exceed 1.2 MeV. This causes the differences in the changes in tan and of the T-8000 material.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 46–49, March, 1974.
