RADIATION EFFECTS IN DIELECTRIC MATERIALS.

Abstract

Some ideas on the theory of polarization in insulators are presented. Several experiments to provide information necessary to develop the theory are outlined. One experiment demonstrates that the rate of buildup and decay of the polarization in sapphire are the same and that the fluence dependence of the polarization is nonexponential. Irradiation of single-crystal sapphire with a high-energy electron beam shows a linear dependence of induced conductivity on dose rate from 5 x 10,000 to 4 x 10 to the 9th power rads (Si)/sec. New sample materials and preparation techniques are discussed. (Author)
